Powder Metallurgy
Prof. Ranjit Bauri · IIT Madras
About
Powder Metallurgy is a very useful manufacturing process which is being practiced in variety of industries for decades. It is a versatile process that can produce a solid, a component or a product in net shape or near net shape staring from a loose mass of powder. This course will not only provide a broad overview of the P/M process but will also deal with the relevant concepts in detail. The objective is to learn about the process and understand it in a scientific and systematic manner.
INTENDED AUDIENCE : Any Interested Learners
PREREQUISITES : Basics of Materials Science & Engineering
