Title:
METHOD OF RENDERING SUPER PLASTICITY TO METAL POWDER AND ALLOY POWDER
Document Type and Number:
Japanese Patent JPS58174504
Kind Code:
A
Abstract:
A method for inducing superplastic properties in nonsuperplastic materials, metals or alloys thus enabling to form them into a desired shape through extrusion or molding at much lower temperatures and pressures.The method of the invention comprises the steps of mixing (10) in powder form the nonsuperplastic material with a second alloy having superplastic characteristics, of compacting (12) the powder mixture into a billet, and of superplastically forming (14) said billet; the grain boundaries of the nonsuperplastic material are subsequently restored by heating (16) of the formed billet to a temperature slightly below the melting point of the second alloy.For use in combination with powder metallurgy techni- ; ques.
