Deep-well drilling has been around for centuries. Over the years, different techniques have been developed in order to improve the efficiency of drilling in a number of different geographical locations. Today’s deep-well drilling industry revolves around the use of bits. In order for this company to be proficient with time and money, it is essential to use bits that are tough enough to withstand impact, while at the same time still possessing a hard surface to protect it against wear.
Case hardening will be the method of choice because of it’s well known ability to create the desired effects of hardness and toughness. Case hardening is a process in which low-carbon steel or iron is carbonized at the surface. The carburized steel part must be machined first in the soft condition, and then hardened by a case hardening treatment to create a hard outer layer. The type of heat treatment used will depend on the contents of the steel. A typical steel alloy for all-around structural purposes is composed of 0.35% carbon. For our case, we will use a chromium steel combination known as No. 5120, which is a much better quality alloy than carbon steel.
The casehardened tool we seek to make will need to be able to withstand high stress impacts and have a hard durable surface to prevent the bit from breaking. Chromium-steel No.5120 is intended to fulfill these exact specifications. The desired levels of carbon and chromium are 0.20% and 0.75%, respectively. In order to accomplish this, the correct heat treatment must be applied. A proven affordable method of casehardening is gas carbonizing. The objective of gas carbonizing is to force a flow of carbonaceous gas between the two plates. The result is a penetration of carbon in less time. The plates are heated by electricity, which allows for a more uniform carbon penetration. The best-known carbon gas used for this process is carbon monoxide because of its ability to rapidly penetrate the metal. A side effect of carbon monoxide is an oxidizing effect that might harm the casehardened metal. To avoid this, the work is packed with wood charcoal in a cylinder. It is then heated to the carbonizing temperature and, a current of carbon dioxide is infused into the cylinder. After the metal has been gas carbonized between 1650 degrees F.

We use metals to construct all kinds of structures, from bridges to skyscrapers to elevators. The strength as well as durability of materials that are crafted out of metal make the materials ideal not only for construction but also for many other applications.
There are many potential adverse health impacts caused by the chemicals used at the drilling site, which are later often unintentional released into the environment. These chemicals are hazardous and as Witter et. al. (2008) state “some of the chemicals used in this process are brought to the surface, potentially contaminating soil, air, and water, while some of the chemicals are left underground, potentially subsurface aquifers” (4). This makes it difficult to track which chemicals are causing effects and where they are coming from. Another piece to the puzzle is that the drilling companies do not disclose the full-list of chemicals so there is a great mystery in what chemicals and what concentrations are used in the process (Lauver 2012:383). However, recently there researchers have begun to breakdown the chemical identities and concentrations.
The high temperature application of Austenitic Stainless Steel is somewhat limited because at higher temperatures it undergoes a phenomenon called Sensitization. According to Ghosh et al. [1], it refers to the precipitation of carbides and nitrides at the grain boundaries. Precipitation of Chromium rich carbides (Cr23C6) and nitrides at the grain boundaries result when the Austenitic stainless steel is heated and held in the temperature range of 500-8500C (773K-1123K). This precipitation of carbides taking place at the grain boundary is because of their insolubility at these temperature ranges. This leads to Chromium depreciated regions around the grain boundaries. So the change in microstructure is takes place and the regions with low Chromium contents become susceptible to Intergranular Corrosion (IGC) and Intergranular Stress Corrosion Cracking (Alvarez et al.) [1, 2]. Along with carbides and nitrides there is formation of chi phase. The chi phase, which is a stable intermetallic compound, consists of Fe, Cr, and Mo of type M18C. Some studies reveal that sensitization may lead to formation of Martensite. In addition to the altered microstructure, mechanical properties of the Austenitic Stain...
The baroque period was during the 1600’s that started in Rome, before spreading quickly throughout Europe. It can be considered a time where a new Art movement flourished as people were expressing themselves in the most creative ways possible. Baroque comes from the Portuguese word Barroco, which means something irregular or strange. At this time, art was being changed. Most of the art of this period is complex, to the point that it evoked feelings towards the “audience”, usually in dramatic ways. Baroque Art wasn’t meant to depict the life style of people at that time, however it is usually noticeable that most of the art have some ties with the catholic religion. While Baroque art is almost its own style, one can compare it to the styles of Renaissance and Neoclassicism. In terms of music, it is believed that Baroque brought about new music styles, including Cantatas, Operas, Canons and Concertos. It is said that the Baroque period end...

By adding up to 2%,of carbon it makes the steel tough and strong. Although it’s tough and strong, it is able to bend. To make sure that the metal doesn’t rust, it has a zinc coating on it. Iron is 26 on the periodic table,and considered an “transition metal,” meaning that it is ductile and malleable, and conduct electricity and heat. ... “Some other elements that are similar to iron are cobalt and nickel. They are the only elements known to produce a magnetic field.” Zinc is 30 on the periodic table and it is also a transition metal like iron. “The first iron used by humans is likely to have come from meteorites.” A meteorite is a meteor that survives its passage through the earth's atmosphere such that part of it strikes the ground. More than 90 percent of meteorites are of rock, while the remainder consist wholly or partly of iron and nickel. Meteors are believed to have been from the asteroid belt of Mars and
In today’s competitive business environment, effective management plays a crucial role. The article Five Minds of a Manager by Jonathan Gosling and Henry Mintzberg, identify some important aspects of effective managers. According to the author, “The world of the manager is complicated and confusing.” Consequently, mangers need to think above ordinary employees. In particular, managers should, think global and act local, collaborate through competitions, be agents of change and maintain order. This paper provides a reflective review of the article Five Minds of a Manager by Jonathan Gosling and Henry Mintzberg.
In management, each of the four functions, planning, organizing, leading, and controlling, are crucial to the development of any business. Involving employees in the planning process help them understand the goals of the organization. Planning is analyzing a situation, determining the goals that will be pursued, and deciding in advance the actions needed to pursue the goals. This paper will evaluate the planning function of the Halliburton Company and analyze the impact that legal issues, ethics, and corporate social responsibilities have on management planning along with examples of each, and analyze three factors that influence strategic, tactical, operational, and contingency planning.
Today many types of drill accessories and tools are used for domestic and commercial tasks. The use of cordless drill accessories prove effective for doing a hole in roofs or walls. In this regard, drill is an ideal item used in many types of applications.

The formation of organization implies that a leader should take the role to control the activities of the group; the work done by the leader is what we call management.
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.
...rbon dioxide, hazardous chemicals, and other pollutants, which can put a hole in the ozone. Also, the usage of some mineral resources can also pollute the air; burning any kind of fuel fossils releases dangerous elements into the air, such as carbon dioxide and carbon monoxide. All of these kinds of pollution which are caused by the increase of technology, can lead to global environmental problems.
Toughness is the ability of a metal to mutilate plastically and to absorb energy in the process before it breaks or fracture. Metals can be heat treated to alter the properties of strength, ductility, toughness, hardness or resistance to corrosion. This can be done by using heat treatment processes which include precipitation strengthening, quenching, annealing and tempering. Annealing and tempering are the most prominent methods for treating metals. A material may become more or less brittle, harder or softer, or stronger or weaker, depending on the treatment used.
