Our world has a long history which separates into different Ages; Stone, Metal, Copper, Bronze and then the Iron Age which still stands to date. Since the metal age, people started to produce metal objects until today, is the most essential object for human during their lifetimes following to our next generations. Due to the fact that no objects are without metals and I dare to say metals are the major motive for development of our world. However in today’s technological era, human still now seems not to insist what happen to our world if there are no more metals. Ergo, it won’t take long before our planet run out of these precious metal as they are non renewable resources. Therefore scientists nowadays using the developed skills of technology are trying to find the solution for replacing the metals with another substance. How can we prevent the absence of metals and any demand for dwindling metals?
Metals can be replaced with similar alternative properties. Thermoplastic is a type of plastic, by applying heat to get a property of liquid and if the melting point is lower than the ...
Every human has a natural tendency to organize. The periodic table is a perfect example of how organization betters the scientific world. Much like a poem, it tells a significant amount of information in a condescended fashion. With this map of the basic elements of the universe, we can find out how many electrons the element has and how much it weighs. Each element has its own separate set of such data; no two elements are the same.
Stainless steel, especially, Austenitic stainless steel, because of their high corrosion resistance and customizable mechanical properties has become an indispensable part of the regularly evolving modern day technology. Stainless steels of various grades find applications in numerous fields starting from the household to the nuclear reactors; from food and beverage cans to construction of different automobile parts. The formation of impervious oxide layer on the surface makes it suitable for use in adverse environments such as sea water.
In this small quaint town on a sunny yet cold afternoon, I sat in and observed this dwelling for several minutes. Watching numerous people walk in and out of this dwelling. Some carried objects in but came out empty handed, while others walked in emptied handed and came out with different sized items. This dwelling is square in shape built in brick, quite large in capacity with double doors, a parking lot with twenty or so spaces for vehicles, and a large metal shape blue object in the parking area. There are also a few square shaped objects on wheels that are being operated by two males. These men carried large plastic bins filled to the brim and placed in the back end of the metal object.
According to the American Council of Chemistry, plastics, which are otherwise known as polymers, are comprised of carbon, hydrogen, chlorine, nitrogen, sulfur, oxygen, and other elements that are combined through the conversion of natural products like oil, natural gas, or coal (ACA, n.d.). Between 7 and 8 % of the oil and natural gasses produced annually are used either directly in the conversion of such fossil fuels to plastics, or in powering the processes to produce plastics (Hopewell, Dvorak & Kosior, 2009). Plastic combinations can either form as thermoplastics, which are plastics whose atoms are connected in long chains that can be melted and reused, or thermosets, which are plastics whose atoms are arranged in three dimensional patterns that cannot be melted or reused (ACC, n.d.). Plastics are used in a wide range of products. For example, polyesters are used in textiles and fabrics, polyvinylidene chlorides are used for food packaging, polycarbonates are used for glasses and disks, and more. By the United States energy averages of 2015, each kg of plastic produced requires 62-108 mega joules of energy. The plastic requiring the largest amount of energy per kg is silicon which required about 235 mega joules of energy per kg. Three hundred and twenty two million metric tons of plastic produced in 2015 alone, and that value continues to raise, (Global plastic production,
"Silver has always been the redheaded stepchild of gold throughout human history (Simpson)." This is due to the fact silver is not as rare as gold or as highly regarded. However, silver has still made a large impact to the economy and population of today. As a large factor in world trade, globalization is due partly to this metal. Today, silver is not only used as an accessory but in many useful things we use day to day. The history of silver encompasses many years, countries and people and is still ongoing today.
The beginnings of modern processing of iron can be traced back to central Europe in the mid-14th century BC. Pure iron has limited use in today’s world. Commercial iron always contains small amounts of carbon and other impurities that change its physical properties, which are much improved by the further addition of carbon and other alloying elements. This helps to prevent oxidation, also known as rust.
Many people view heavy metal as loud, obnoxious music played by people with no talent and listened to by a bunch of head banging punks who do not like listening to “real music”. But many people do not know anything about heavy metal or its history. Heavy metal is a term widely characterizing a style of music that is loud, aggressive, and extremely popular. Heavy metal is extremely diverse and has many sub genres which is why not all heavy metal bands sound the same. Many different heavy metal bands and sub genres originate from all over the world. During its 40-plus-year history, heavy metal has outlasted many trendier genres and continues to evolve and become popular today.
Stainless steel is a type of alloy that has a very strong lattice structure (an arrangement/ shape of the crystals or other objects) which in some case can be more beneficial than others depending on the type of application it may be used for. In many cases this structure will make the material more suited to being used in engineering applications such as tools for instance a hammer (stainless steel alloys) , also they can be used for gears, engines, electrical motors and hydraulic systems because the structure makes the material so strong. So when the arrangement of the structure is as above it makes the overall material even stronger which makes it a good for all the applications stated above. I believe its strength and durability are its main properties as these are commonly needed in the engineering industry, although it is also very well known to be used for its corrosion resistance as it is resistant to many types of corrosion. It is used for these properties because the components such as gears need to be strong in order to keep transferring and altering the rotary motion and torque exhibited in the machine that it may be used in, durable to withstand any loads or pressure put onto it and also corrosion resistance to give the components a bigger life span and increase its rate of work throughout its required use.

By recycling metals you can save energy, money and the environment. Here’s the thing metal is not grown it doesn’t pop up in rows it’s a resource that can be used up. In order to obtain metal first it has to be mined which in this form is called ore, then it is smelted and purified. This process alone can create a lot of pollution and can be very wasteful. Wasting Metal just throwing it away is probably one of the most hazardous and costly waste that a person can create. Some metal contains lead which in the state of California is known to cause cancer secondly the process to make metal is time consuming. As listed above metal can be taken to scrap yards to be recycled not hard to do. Load it up take to a scrap yard unload and get paid and get out. By recycling metal you are doing you and everyone else a great service. You help the environment by not allowing it to absorb hazardous waste such as lead. And you don’t let a precious resource go to
From the beginning of time, the earth has provided its inhabitants with everything needed to sustain life at its most basic level. For instance, the ratio of land to fresh water as well as Earth’s natural cycles provided enough resources for animals to survive. Unfortunately, as the human population grew, the previously abundant natural resources started to become limited. In fact, engineers have recently been tasked with discovering new methods of harnessing energy, harvesting food, and collecting fresh water because the population is quickly depleting traditional techniques. Not only is the sheer number of people on Earth using up all of its natural resources, but humans’ modern desires are furthering the destruction of Earth. In developed
Metals possess many unique fundamental properties that make them an ideal material for use in a diverse range of applications. Many common place things know today are made from metals; bridges, utensils, vehicles of all modes of transport, contain some form of metal or metallic compound. Properties such as high tensile strength, high fracture toughness, malleability and availability are just some of the many advantages associated with metals. Metals, accompanied by their many compounds and alloys, similar properties, high and low corrosion levels, and affects, whether negative or positive, are a grand force to be reckoned with.
Metallurgy is the field of materials science and material engineering that studies the physical and chemical behaviour of metallic elements, their microstructure compounds and their mixtures, which are mostly known as alloy. Metallurgy can be refers as the technology of metals where science is applied to the production of metals, and the engineering of metal components for the uses of products for consumers and manufacturers.
In our days, mining for resources is inevitable. The resources we need are valuable in everyday life. Such resources mined up are coal, copper, gold, silver, and sand. However, mining poses environmental risks that can degrade the quality of soil and water, which can end up effecting us humans if not taken care of and many of the damages are irreversible once they have occurred.
Resources is the obvious answer, but what resources exactly? The future is likely to have several technological breakthroughs that may change what resources are needed. If people from 2000 years ago had tried to leave resources for us, they likely would have left very different materials than what we actually use and have a need for today. This problem also means that if we were to constrict uses of materials, we could potentially be robbing them of the materials needed for a technological breakthrough that could make said limited materials obsolete. If someone had restricted resources during the industrial revolution then we possibly could of had a very different set of technology today. Something to also consider is what kind of lives our future generations will be living- we do not know what kind of conditions they will be living in, and even scientific guesses can only go so far (and many predictions about the future have been wrong before). Simply put, we have no way of knowing what kind of environment our future generations will be living in, so we need to consider a wide range of possibilities. It is also of the utmost importance that our future generations have lives that are at a decent living standard, because as Pauli Becchi writes- “The perpetuation of human life on the planet would be pointless if it came at the price
