Age hardening, also known as precipitation hardening, is a type of heat treatment that is used to impart strength to metals and their alloys.
Decarburization is a surface degradation phenomenon in the forging and heat treating of steels. Decarburization may be described as a metallurgical process in which the surface of steel is depleted of carbon by heating above the lower critical temperature or by chemical action.
Descaling is a process of removing oxide deposits from a heated stock, either before or during forging operations. Physical methods for descaling include use of wire brushes, extra blows, scraping devices, polishing or blasting.
Auxiliary operations are those processes that are performed on forgings to obtain properties like surface conditions or shapes that cannot be achieved in regular forging operations.
Swedish researchers have conducted an experiment that confirms the existence of a new artificial element with an atomic number of 115 - temporarily named ununpentium.

Spheroidizing is a form of heat treatment of iron-based alloys, which is done at temperatures that are slightly below the critical range and followed by a slow cooling process. The process of spheroidizing is a specific heat treatment of steels, mainly carbon steel.
Press forging may be defined as the process of shaping a metal that is placed between two dies by applying mechanical or hydraulic pressure.
Rockwell hardness testing is a method of determining the relative hardness of a material. In this test, hardness is measured by determining the depth of residual penetration by a steel ball or a diamond point under load.
3D printing and additive manufacturing has the potential to be used within space travel.
