鉴于颗粒增强钛基复合材料在提高强度的同时会引起塑韧性的下降，借鉴性能优异生物材料的叠层微观结构，利用粉末冶金结合热加工工艺（热锻+退火）的方法，制备了增强体体积分数为5%~15%的原位合成层状Ti-（TiB+TiC）/Ti复合材料，并对其组织和力学性能进行了研究。结果表明：复合材料组织完全致密化，复合层中团聚的增强体被分散，纯钛层α晶粒沿锻造方向排列；复合材料的室温抗拉强度较纯钛的提高近一倍，退火后其伸长率明显提升；随增强体体积分数的增加，复合材料的强度稍有提高，但塑性下降较为明显，增强体体积分数为5%的复合材料具备优异的综合力学性能，与增强体体积分数为15%的复合材料相比，强度仅降低了4%，但伸长率却增加了3.8倍。
