Physical metallurgy deals with the physical and mechanical properties of metals and alloys. It studies the behaviour of metals under different conditions, such as temperature, pressure, and stress. This field of metallurgy also involves the study of phase transformations, microstructure, and grain boundary behaviour.

2. Extractive Metallurgy

Extractive metallurgy deals with the extraction of metals from their ores. It involves various processes, such as mining, milling, smelting, refining, and electrolysis. This field of metallurgy aims to separate the desired metal from impurities and contaminants to obtain a pure and usable form.
