Abstract

A composite consisting of Al matrix and giant magnetostriction particles was fabricated by powder metallurgy. The composite was heat treated under a magnetic field to produce compressive residual stress in the matrix due to the giant magnetostriction inside particles. Tensile tests revealed that the above magnetization heat treatment improved the yield strength of the composite. The strengthening mechanism based on magnetostriction was discussed using micromechanics analysis.
