Executive Summary

Statistical analysis was done on the aluminum manufacturing data. Using appropriate tests, some relationships were established. First, sheet metal grade aluminum has the highest production output at sections 1 and 2. However, the standard deviation values are also highest at these two sections. Second, there is evidence that the produced amount of electrical grade aluminum is significantly different (probably higher) than the sheet metal grade aluminum made. Third, there is evidence that the bauxite consumption the bauxite consumption is significantly different (probably higher) than the purchasing policy of 4.2 tons per pot. Lastly, power Continue reading...

Metal Distribution The use of information technology has increased tremendously over the years. Today, we use technology in all areas of our lives both personal and business wise. In the distribution of metal, the use of service metal centers has become the norm in the industry. Manufacturers of metal together with the end users have chosen to focus on specific areas (Forging, n.d). The manufacturers specialize in producing metal and steel while the end users focus on designing their products leaving the rest of the work to be done at the call centers. The work done at the service Continue reading...

Abstract:

The total hip replacements are indispensable medical procedures that address the hip problems of people. The medical practice for some time has been an adequate solution for hip problems. However, problems has been discovered that the materials used for the implants that are composed of metals and alloys cause fretting corrosion which leads to various health complications and implant failure. This paper discusses the hip joint implants and the fretting corrosion that complicates the medical practice. It touches the adverse effects of the implant corrosion in the health of the patients. Furthermore, this paper divulges some of the design Continue reading...

(Professor/Instructor)

The volume production of inexpensive steel products realized by the processes alongside those of Bessemer’s has recast the world. Cost effective steel products has allowed manufacturers to design and develop a host of large and small products using steel as a base material. Inclusive of these products are ships, aircraft, buildings, forks, spoons, witches, razors, saws, and tools and utensils of every type (Spoerl 1).
The systematized and inexpensive production of steel became feasible only after the development of the Bessemer method, named after its ingenious inventor, British metallurgist Sir Henry Bessemer. Bessemer posited that the presence Continue reading...

Introduction

Metals has played crucial role in the development and improvement of modern and historical society. Metal resources are derived from the earth’s crust or from recycling of the metal discarded after their use in the economy. When the used metals are not efficiently recovered from the economy, people will increase their use of the primary resources and therefore affecting the nature by increasing various metals dispersions in the ecosystem (environmental pollution). Industrial society values the use of metals such as aluminium, because of their useful properties such as strength, (Wernick and N.J. Themelis, 1998).
Among the earth’s Continue reading...

Abstract

For centuries, mining has been taking place in different parts of the world, from the shallow waters, deep waters and even on dry land. Some mining activities having been a result of natural happenings such as flooding, while others have been a result human activity, which leads to environmental degradation that in return leads to discovery of metals and minerals, such as soil erosion. However, for the existence of some minerals to be discovered, it was influenced by the human nature of curiosity or through scientific experiments. The Tamar Valley Region, North of Plymouth in Southwest England is one Continue reading...

Introduction

The paper analyzes the ethical issues involved in China’s mining of rare metals. Over the years, China has significantly been reducing its export and supply of ‘green products.’ Such products include electric products that are energy efficient. The reason for this has greatly been influenced by the Chinese Ministry of Industry and Information Technology’s policy of regulating the amount of certain rare metals that are exported. The government has further imposed complete bans on the export of other metals. China is rated as the world’s number one producer of rare metals and manufacture of products that Continue reading...

Section 1: Catalysis

Introduction
Catalysis is a process by which chemical reactions are hastened by small amounts of external substances, called catalysts. A suitable catalyst can alter the rate of a thermodynamically attainable reaction, but cannot disturb the position of thermodynamic equilibrium. Most catalysts are solids or fluids, however they may likewise be gasses. Catalysis is a cyclic process. The reactants form a chemical complex with the catalyst, subsequently opening a pathway for their conversion into the respective products, following which the catalyst is released and allows the cycle to continue. Now, catalysts do not have infinite lifetimes. As a result of Continue reading...

Paper punching

The technology in the modern world on how information is received and stored is highly revolving. However, relevant documents ought to well be saved for future reference. Experts declare that the spiral binding and demand on printing is set to experience massive expansion in the future and hence the need to explore the technology employed in the paper punching.
Paper punching is very crucial as it prepares the documents for proper archiving and hence easy retrieval in the future. There are several factors that affect the quality of a paper punch. In order for one to produce a good Continue reading...

Question 1: (Metallic Materials)

Recrystallization:
This is the process of growth of grain fragments in an alloy when it’s being worked on. This affects materials properties and services while in use.
Examples such as steel’s properties are affected such that there is reduction in strength and hardness of the material and this affects its applications and behavior in service. Other materials such as copper are affected in the same way.

Hot or cold working:

Hot or cold working involves hardening of materials and also and also heating the material. Iron is an example and is affected by hot working where it can be cast in Continue reading...
