摘要

This study investigated the microstructure, mechanical properties, and fracture mechanism of a TiB/TA15 composite material. The TiB phase exhibited a quasi-continuous distribution at the grain boundaries of TiB/TA15, playing a role in pinning and grain refinement. The tensile strength of the material is greatly increased by 28.8% relative to that of TA15, from 875 to 1127 MPa, and the fracture mechanism is mixed fracture. This study also conducted thermal cycling at 650 °C for 2 h. After 1, 5, and 10 thermal cycles, the tensile strength decreased. However, it only decreased by 8.7% after 10 thermal cycles, which indicates that temperature fatigue had little effect on the mechanical properties.
