Abstract

Formation of PFZ layers around reinforcements and simultaneous precipitation of the equilibrium phase on the interface has been clarified. Also the segregation of the solute atoms in the vicinity of the reinforcements is analyzed in this study. Effects of the PFZ layer and the solute atom segregation in the vicinity of the reinforcement in the discontinuously-reinforced metal matrix composite on deformation behavior and strength are analyzed by means of non-linear finite element method. With a view of eliminating baneful effects exerted by the formation of the PFZ layer which are predicted by the FEM analysis, new heat treatment procedure which has been developed to control the matrix microstructure by a simple heat treatment process is introduced. Improvement of the mechanical properties in this microstructurally-controlled MMCs is also reported in this study.
