HEAT-RESISTANT ALLOY AND MANUFACTURING METHOD THEREFOR

摘要

Provided is a heat-resistant alloy that satisfies physical properties such as proof stress and hardness adapted to an increase in the melting point of a welding object compared to conventional alloys. A heat-resistant alloy of this invention includes a first phase, as a main component, containing a Mo or W metal phase, a second phase containing a Mo-Si-B-based alloy, and a third phase containing titanium carbonitride, wherein the balance is inevitable compounds and inevitable impurities.
