Abstract

Three refractory metal composites were prepared by powder metallurgy, that is. W–7Cu, Mo–10Cu and W–26Re. Properties of the materials were studied, such as tensile strength, fracture toughness, elastic modulus and ablation resistance. The results show that W–26Re has the best mechanical properties and ablation resistance. The tensile strength is 350 MPa at 1600 °C. And the linear ablative ratio is 3.37%, and the linear ablative rate is 0.006 mm/s at 2500 K of ablation of 600 s. It has wide potential application in the high-temperature working environment.
