Beschreibung
Zusammenfassung:	Disclosed herein are improved chromium carbide alloy which possess improved properties as related to previous developments. The utilization of aluminum in the alloy can enhance the high temperature oxidation resistance. Embodiments of alloys were designed to simultaneously possess 1) a low liquidus temperature which enables easy atomization on an industrial scale, and 2) a microstructure of a gamma matrix and Cr7C3 carbide precipitates which enables high temperature stability and retention of advantageous properties at high temperatures.
