Abstract
Disclosed herein are embodiments of wear resistant alloys, such as ferrous alloys, that can have reduced carbide contents. In some embodiments, the alloys may have no carbides. In some, the alloy may have boride phases, such as phases having high Mo+W content and/or high Fe+Cr content. There can be reduced hardphases levels out of the specifically disclosed boride phases in some embodiments. In some embodiments, hypereutectic chromium borides can have limited incorporation into the disclosed alloys.
