Tungsten alloys containing A15 structure and method for making same

摘要

A hard fine-grained internally stressed material of tungsten and carbon or tungsten, carbon and oxygen is described which is produced by thermochemical deposition. The material consists primarily of a two phase mixture of pure tungsten and an A15 structure, is free of columnar grain distribution, and has a hardness of greater than 1,200 VHN. The average grain size is less than 0.1 micron.
