Jan 21, 2015Aluminum is the most abundant metal and the third most abundant element, after oxygen and silicon, in the earth's crust. It is widely distributed and constitutes approximately 8 percent of the earth's surface layer. However, aluminum is a very reactive element and is never found as the free metal in nature. It is found combined with other elements, most commonly with oxygen, silicon, and fluorine.

Steel and aluminum processing will be studied to understand fundamentals such as the impact of impurities and phase transformations. The study of processing will provide an understanding of how the final properties are influenced by the sequence of processes from the extraction of metal from ore, through casting, hot deformation and heat treating.
