The results revealed that the propagation mode of main crack related to the orientation of powder boundaries when the specimen fractured. For the specimen tensed along extrusion direction, the microcracks along rolling plane did not affect propagation of the main cracks; the microcracks along vertical section might lead to unusual fracture; the cross-section boundaries are ready to become the low energy propagation path for main crack. Hot rolling improved cohesion strength for boundaries along the vertical section and cross-section more than ones along rolling plane, resulting in the change of fracture mode at a certain deformation (30%). The different variation regularities for fracture strength and elongation relate to the fracture mode and follow-on deformation hardening.
