Outline of Final Research Achievements

Fragmentation behavior of secondary particles by severe plastic deformation (SPD) for multi-phase materials containing platelet particles or spherical particles is investigated. The fragmentation and the distribution change of secondary particles are induced only in the multi-phase materials with platelet particles. Moreover, the distribution of the platelet particles in the multi-phase composite is determined by material flow of matrix induced by SPD. Hence, particle distribution and mechanical property of the SPDed multi-phase materials can be controlled by considering the material flow of the matrix.
