Abstract A study was made of the off-axis tensile properties of γ/γ'-a-Mo DS eutectic and of observation of the dynamic fracture process by SEM. If the loading direction deviates from the Mo fibre growth direction, the tensile strength and ductility decrease gradually. During the loading process, two types of cracking are observed: one is cracking of the fibre, and the other is delamination along the fibre-matrix interface. In plastic deformation, slip can pass through both the matrix and the fibre. As a rule, the thicker fibers are cracked earlier than the thinner ones, because they have less defects and better ductility. Delamination is the main source of final fracture.
