摘要
Abstract
Tungsten infiltrated copper composites and molybdenum infiltrated copper composites were prepared by infiltration,the grades are W-7Cu and Mo-10Cu.Properties of the materials were studied,such as tensile strength,fracture toughness,elastic modulus and ablation resistance.The results show that the tensile strength and ablation resistance of W-7Cu are better.The tensile strength is 728 MPa at 25 ℃ and 86 MPa at 1 600 ℃,the linear ablation rate is 0.231 mm/s at 2 500 K.Mo-10Cu has better toughness,the fracture toughness at room temperature is 41MPa · m1/2关键词
