METHOD FOR PREDICTING MECHANICAL CHARACTERISTIC OF ALUMINUM ALLOY MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a method for predicting the mechanical characteristics of an aluminum alloy member that is manufactured by a powder metallurgy method also for a site that cannot be tested and evaluated by the conventional method. SOLUTION: The average value of aspect ratio a/b in a raw material aluminum alloy particle that is observed in a material organization in a surface in parallel with an orientation for giving mechanical characteristics is obtained to a member that is manufactured by hardening the raw material aluminum alloy powder, and the average value is used as an index, thus predicting the mechanical characteristics of a required site.
