METHOD FOR PRODUCING DUAL-PHASE HYDROGEN PERMEABLE ALLOY, AND DUAL-PHASE HYDROGEN PERMEABLE ALLOY

摘要

PROBLEM TO BE SOLVED: To produce a dual-phase hydrogen permeable alloy composed of a phase having hydrogen permeability and a phase having hydrogen embrittlement resistance by using a powder metallurgy process.;SOLUTION: Regarding the method for producing a dual-phase hydrogen permeable alloy composed of a phase having hydrogen permeability and a phase having hydrogen embrittlement resistance, through a first stage where two or more kinds powder raw materials are selected, and they are mutually mixed; a second stage where the powder raw materials are pressurized in a vacuum, so as to produce a green compact; and a third stage where the green compact is subjected to heating treatment, the phase having hydrogen permeability and the phase having hydrogen embrittlement resistance are formed.;COPYRIGHT: (C)2008,JPO&INPIT
