摘要
A 30 vol.% ZrCp/W composite has been deformed in compression in the temperature range of 1200-1600 degrees 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 degrees C. The formation mechanisms of the dislocation configurations are studied.
