摘要：

ZrC-TaC composites synthesized via Displacive Compensation of Porosity method 1300 degrees C using porous TaC preforms and Zr-Cu binary melts (Zr2Cu, ZrCu and Zr14Cu51) are presented in this work. Effect of Zr content in the infiltration on microstructure is investigated by XRD, FE-SEM and TEM analysis. The results indicate that ZrC and platelet-like Ta2C formed during the reactive infiltration of Zr-Cu melts into TaC preforms. The nano precipitations in TaCx/ZrC grains and Ta atoms dissolved in ZrC suggests a probable dissolution-precipitation mechanism of the reaction between Zr-Cu melts and TaC. The ZrC-TaCx composite exhibits a flexural strength of 142 MPa and a fracture toughness of 5.34 MPa m(1/2). The platelet-like Ta2C phase has toughening effect by crack deflection and bridging.
