Title:
METHOD FOR PRODUCING ALLOY MEMBER
Document Type and Number:
Japanese Patent JP2019178427
Kind Code:
A
Abstract:
To provide an alloy member that has excellent homogeneity of an alloy composition and a fine structure and also excellent shape controllability, by using a high entropy alloy having high mechanical strength and high corrosion resistance, a method for producing the same, and a product obtained using the alloy member.SOLUTION: An alloy member has a chemical composition that contains each element of Co, Cr, Fe, Ni, Ti in a range of 5 atom% or more and 35 atom% or less, and contains Mo in a range of more than 0 atom% and 8 atom% or less, with the balance being unavoidable impurities. In the host phase crystal, ultrasmall particles with an average particle size of 100 nm or less are dispersed and deposited.SELECTED DRAWING: Figure 4B
