PROCESS FOR PRODUCING HEAT RESISTANT MEMBER MADE OF NICKEL-BASED ALLOY OR IRON-BASED ALLOY

摘要

To provide a process for producing a heat-resistant member made of nickel-based alloy or iron-based alloy that has a significantly improved thermal fatigue resistance compared to conventional ones.SOLUTION: The process for producing a heat-resistant member made of a nickel-based alloy or iron-based alloy of the present invention includes: a mechanical property improving agent addition step 1 in which a metal powder for improving mechanical properties of the final product heat-resistant member is mixed into a powder made of nickel-based alloy or iron-based alloy; a molding step 2 in which an alloy powder mixed with a metal powder in the mechanical property improving agent addition step 1 is molded; and a sintering step 3 in which a compact molded in the molding step 2 is sintered to yield a heat-resistant member.SELECTED DRAWING: Figure 1
