Abstract

An apparatus and method of mechanical milling and grinding of various materials at temperatures ranging from sub-ambient conditions to well-below their ductile-brittle transition temperature (DBTT) are presented. In one embodiment the present invention entails the design of a cryogenic milling chamber compatible with horizontal high-energy mills. The new design and configuration of the milling vessel provides robust and efficient cryomilling of various materials with no contact between the cryogen and the powders. Some embodiments of the invention improve the heat removal rate from the non-uniform heat load generated by the impact energy deposited into the chamber wall by the milling media.
