Abstract

A 30 vol.% ZrCp/W composite has been deformed in compression in the temperature range of 1200-1600°C. Dislocation nucleation mechanism in ZrC particles is discussed by analyzing the harmonious deformation between tungsten-matrix and ZrC particles. Thermal activation apparently increases the mobility of screw segments, resulting in the formation of many kinetics jogs and thermodynamics jogs above 1300°C. The formation mechanisms of the dislocation configurations are studied.
