Metallurgy is a relatively broad and, at times, complex subject. It serves an important purpose in a number of industries, especially in regards to quality control. 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 desired properties may be electrical, mechanical, magnetic, or chemical in nature; all of them can be enhanced by alloying and heat treatment. History of metallurgy. Metal parts can be made in a variety of ways, depending on the shape, properties, and cost desired in the finished product. Medical. Mining and Metallurgy served, and continue to do so, a crucial role to the advancement of the economy, labour, infrastructure, technology and etcetera in pre-industrial African societies as I am yet to analyse. Most welders do not need to be experts. 1) that studies the physical and chemical behavior of metallic elements, their intermetallic compounds and their alloys. The present-day use of metals is the culmination of a long path of development extending over approximately 6,500 years. Metallurgy is the part of materials science and materials engineering (Fig. Metallurgy - Metallurgy - Physical metallurgy: Physical metallurgy is the science of making useful products out of metals. Because welding involves the heating and cooling of metals, and the heating and cooling of metals affects the mechanical properties of the resulting part. Learn more about the value of powder metallurgy in the automotive market. Importance Of Metallurgy In The Sub-Saharan Africa 1055 Words | 5 Pages. The Precision of Powder Metallurgy. Why? It is generally agreed that the first known metals were gold, silver, and copper, which occurred in the native or metallic state, of which the earliest were in all probability nuggets of gold found in the sands and gravels of riverbeds. However, all welders should have a good grasp on basic metallurgical principals. As lightweighting becomes more important to automotive manufacturers, the ability to customize materials becomes even more advantageous. Metallurgy is the science and study of the behaviors and properties of metals.
