| Abstract: | To deal with the structure and mechanical properti4es of TiCp-AlNp/Al composites on the tensile condition at elevated temperature, and detail the effect of temperature on the yield strength of TiC -Al composites. Along with micrograph of fractured surfaces of composites tensioned at different temperatures, the authors discuss the fracture mechanism of the composite and micro-mechanism of enhancer matrix of AIN during tensioning at elevated temperature. |
