Title:
HIGH ENTROPY ALLOY MEMBER, METHOD FOR PRODUCING ALLOY MEMBER, AND PRODUCT USING ALLOY MEMBER
Document Type and Number:
WIPO Patent Application WO/2017/098848
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a high entropy alloy (HEA) member which uses a high entropy alloy having high mechanical strength and high corrosion resistance, and has excellent uniformity of alloy composition and microstructure and excellent shape controllability; a method for producing the HEA member; and a product using the HEA member. The HEA member according to the present invention is an alloy member comprising an HEA, and is characterized by having a chemical composition containing elements Co, Cr, Fe, Ni, and Ti, each within the range of 5-35 atom%, and Mo within the range of more than 0 atom% but not more than 8 atom%, the balance being unavoidable impurities, and is characterized in that, in the alloy member, an intermetallic compound phase of needle-like crystal is dispersed and deposited in parent-phase crystal.
