采用碳热还原法制备了不同W含量的(Ti1-x,Wx)C固溶体(摩尔分数x=0.00,0.07,0.17,0.32),研究了反应温度对产物的物相组成和(Ti,W)C粉末特性的影响,并以(Ti1-x,Wx)C为硬质相制备了(Ti1-x,Wx)C-20Ni金属陶瓷,对其组织和力学性能进行表征.结果表明:随着温度升高,TiO2和WO3被逐步还原并碳化;(Ti1-x,Wx)C固溶体粉末的晶粒尺寸和晶格参数均随W含量的提高而降低;(Ti1-x,Wx)C基金属陶瓷组织中无明显芯/环结构,随着W含量的提高,陶瓷晶粒细化、孔洞数量减少、组织更均匀;当W含量为x=0.17,0.32时,其综合力学性能较好. (Ti1-x, Wx) C solid solution with different W content (mole fraction x = 0.00,0.07,0.17,0.32) were prepared by carbothermal reduction method. The effects of reaction temperature on the phase composition and (Ti1-x, Wx) C-20Ni cermets with (Ti1-x, Wx) C as the hard phase were prepared and their microstructures and mechanical properties were characterized.The results show that with the temperature (Ti1-x, Wx) C solid solutions. The grain size and lattice parameters of (Ti1-x, Wx) C solid solution powders decrease with the increase of W content. There is no obvious core / ring structure in the microstructure. With the increase of W content, the grain refinement of ceramic decreases the number of holes and the microstructure is more uniform. When W content is x = 0.17,0.32, the mechanical properties are better.
