The science and technology of metals and alloys. Process metallurgy is concerned with the extraction of metals from their ores and with refining of metals; physical metallurgy, with the physical and mechanical properties of metals as affected by composition, processing, and environmental conditions; and mechanical metallurgy, with the response of metals to applied forces. The science or procedures of extracting metals from their ores, or purifying metals and of casting useful items form the metals. It involves knowledge and study of metals and their phases and properties at bulk and atomic levels.
