Biohydrometallurgy is a technique in the world of metallurgy that utilizes biological agents (bacteria) to recover metals. It is a subset or specialized form of hydrometallurgy, which refers to the use of aqueous solutions for metal extraction through a series of chemical reactions. Bioleaching is closely related to biohydrometallurgy. It focuses on extraction or liberation of metals from their ores through the use of living organisms.

A prill is a small aggregate or globule of a material, most often a dry sphere, formed from a melted liquid through spray crystallization.

concept is used on ferrous materials, typically steel and cast iron, to determine various properties of the alloy when more than just carbon is used as an alloyant, which is typical

A scleroscope is a device used to measure rebound hardness. It consists of a steel ball dropped from a fixed height. The device was invented in 1907. As an improvement on this rough method, the Leeb Rebound Hardness Test, invented in the 1970s, uses the ratio of impact and rebound velocities (as measured by a magnetic inducer) to determine hardness.

Brinelling is the permanent indentation of a hard surface. It is named after the Brinell scale of hardness, in which a small ball is pushed against a hard surface at a preset level of force, and the depth and diameter of the mark indicates the Brinell hardness of the surface. Brinelling is permanent plastic deformation of a surface, and usually occurs while two surfaces in contact are stationary (such as rolling elements and the raceway of a bearing) and the material yield strength has been exceeded.
