Aluminum is used in many of our household items. From pie pans to pop cans, Aluminum is a very common product. Charles M. Hall is an American Chemist who figured out how to produce aluminum using his electrolytic method. This method allowed aluminum to be mass produced. Hall was born on December 6th, 1863 in Thompson, Ohio. His father was a missionary and minister who was very educated. Education played a big part in his childhood. He read numerous science magazines and articles as a child. He…

Study of Stress Corrosion Cracking (SCC) in Alloys Jiang Jingxing 1. Introduction of Stress Corrosion Cracking Stress Corrosion Cracking (SCC) is the growth of cracks with a under the combined effects of a static stress and a specific chemical environment. All SCC failures involve a macroscopic brittle performance, and the ductility of the material is reduced. It is universally acknowledged that there is no single mechanism for stress corrosion cracking (Ford, 1984). Stress…

Glenn T. Seaborg was born in Ishpeming, Sweden in 1912, into a family known publically as being intelligent. However, in 1922, the family moved to California in order to expand their opportunities. In high school, he had no interest in science. However, a science class was required for graduation. A teacher named Dwight Logan Reid is given credit for his interest in the field. Due to his family’s finances, the nearby University of California at Los Angeles (UCLA) was his only option; due to its…

of glucose on the dissolution of these metal ions. The scope of this project could only focus on the effect of one variable; whether in fact, many other variables such as pH, salinity, and phosphate ions could also affect the dissociation of NMC particles. However, by focusing on one variable at time, a more general hypothesis could be drawn and utilized in the treatment of waste batteries. Background information on how glucose could form complexes with metal ions were studied from the Dolezal…

Question 1 Part A: General Topic Properties of stainless steel • Corrosion resistant • Good tensile strength • Good low and high temperature service • Appearance • Hygienic • Has a respectable friction coefficient Corrosion resistant Stainless steel has a chromium-rich rust protective oxide thin film on the surface known as a passive layer, in which prevents corrosion by blocking oxygen diffusion to enter the passive layer and spreads rust into the internal material. As seen in Figure 1,…

A number of pairs of rolls are the components of a typical roll former. Each pair of rolls which are rotating in the opposite direction changes the shape of the sheet once the sheet passes through the rolls. The complexity of the section determines the number of pairs required. Forming speeds vary between 20-40 meters per minute and that’s why it’s a rapid method. Computers hold control of the rolling machines and a flying…

the mines. The rocket was a great success and he was famous for his rocket and what he had done/gone through to build it. The rockets purpose is to go into space or just very high in the air. It was built to go extremely high. With the special metal and fuel that…

process that changes over a refined metal to a more chemically stable shape, for example, its oxide, hydroxide, or sulfide. It is the slow destruction of materials (generally metals) by a chemical reaction caused by the environment. Corrosion is basic to ponder in two perspectives. Right off the bat, financial, which including the lessening of material misfortunes coming about because of the squandering ceaselessly or sudden disappointment of funnelling, tanks, metal segments of machines, ships,…

Silicon carbide has been recognised as an important structural ceramic material because of its unique combination of properties. It is a promising ceramic material that can replace conventional metals and ionic-bonded oxide ceramics such as alumina. Structure of Silicon carbide Silicon carbide is a compound of silicon, a metalloid, and carbon, a nonmetal, and has a giant molecular lattice structure. It has a similar structure with diamond. Each carbon atom is joined tetrahedrally to four…

Steel plate has become widely used in the construction and manufacturing industries, and projects cannot exist without it. What many people fail to realize is how not all steel plate has been created equal. In fact, a lot of steel plate grades have unique traits that will make them better for more specific applications. For example, structural steel grade A514 T-1 has been designed so that it has been heat treated. That means that you have higher strength capabilities, and it will weld better.…
