Metallurgy - Metallurgy - Physical metallurgy: Physical metallurgy is the science of making useful products out of metals. It serves an important purpose in a number of industries, especially in regards to quality control. As lightweighting becomes more important to automotive manufacturers, the ability to customize materials becomes even more advantageous. Metallurgy is a relatively broad and, at times, complex subject. Medical. However, all welders should have a good grasp on basic metallurgical principals. The Precision of Powder Metallurgy. Why? Hari om, you are asking a question as to : “What is the importance of engineering metallurgy and materials to a mechanical engineer”.Hari om. The present-day use of metals is the culmination of a long path of development extending over approximately 6,500 years. Metal parts can be made in a variety of ways, depending on the shape, properties, and cost desired in the finished product. Because welding involves the heating and cooling of metals, and the heating and cooling of metals affects the mechanical properties of the resulting part. 1) that studies the physical and chemical behavior of metallic elements, their intermetallic compounds and their alloys. Most welders do not need to be experts. The desired properties may be electrical, mechanical, magnetic, or chemical in nature; all of them can be enhanced by alloying and heat treatment.
