Abstract
A manufacturing method of oxidation resistant alloy includes: producing a first formed member by applying compression forming to metal powder; and applying compression forming to the first formed member in a state in which the first formed member is covered with alloy powder different from the metal powder. The oxidation resistance of the major constituent of the alloy powder is higher than the oxidation resistance of the major constituent of the metal powder. Producing the first formed member may include applying the compression forming to the metal powder without melting the metal powder. Applying the compression forming to the first formed member may include: producing a second formed member by applying compression forming to the alloy powder without melting the alloy powder; and sintering the second formed member.
