“…Non uniformity of deformation of two-phase material was reported by many investigators using fractographic and metallographic techniques [1][2][3][4][5][6][7][8][9][10][11]. Different stages of deformation, crack initiation, crackgrowth, crack propagation were examined [1][2][3][4][5]. The effect of particle properties: size [5][6][7][8][9][10][11][12], volume fraction [11][12], shape [12,13], and interparticle spacing [5,9], on the deformation process was studied.…”
