Cold Grinding with the pin mill (Cryogenic Milling) Cryogenic Milling is a process to reduce particles by means of mechanical force as well as embrittlement of the material by means of cooling by liquid nitrogen. Thus, the fracture behaviour of viscous or elastic materials is transferred into the state that a grinding/ milling is possible.

Tempering (metallurgy) - Wikipedia
Tempering is a process of heat treating, which is used to increase the toughness of iron-based alloys.Tempering is usually performed after hardening, to reduce some of the excess hardness, and is done by heating the metal to some temperature below the critical point for a certain period of time, then allowing it to cool in still air. The exact temperature determines the amount of …
