英文摘要	Tungsten reinforced W2Ni3Si matrix in situ composites consisting of primary tungsten dendrites and the interdendritic W2Ni3Si ternary metal silicide were fabricated by the Lasmelt(TM) process using a newly patented laser melting furnace. Microstructure of the laser melted W/W2Ni3Si composites was characterized by OM, SEM, XRD and EDS. Room and high temperature wear properties were evaluated under metallic sliding wear test conditions and the wear mechanism was discussed. Because of the unique combination of high strength and ductility of the tungsten reinforcing phase and the high hardness and strong intermetallic atomic bonds of the ternary metal silicide W2Ni3Si matrix, the W/W2Ni3Si in situ composites have excellent wear resistance under both room and high temperature sliding wear test conditions.; Metallurgy & Metallurgical Engineering; SCI(E); 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 0; ARTICLE; 7; 767-770; 39
