Abstract

The high-temperature deformation and fracture behavior of molybdenum/partially stabilized zirconia composites prepared by powder metallurgical route, was evaluated up to 1573 K by means of modified small punch test (MSP). The results of the dependence of MSP load-deflection curve on temperature have shown apparent transitions in the deformation and fracture of the composites: that is, every composite, which is brittle at room temperature, turns into ductile above a certain critical temperature and shows the similar load-deflection curve to those obtained in the case of ductile metallic materials.
