摘要(Abstract)：

向钛合金中引入均匀分布的增强相可以提高其强度和刚度，但是不可避免地会引起塑性和韧性的下降。受自然界珍珠贝壳结构和组分的启发，以纯钛片作为金属层材料，钛粉与碳粉作为强性层材料，采用放电等离子烧结法成功制备出Ti-TiC/Ti层状复合材料，并探索了烧结温度对Ti-TiC/Ti层状复合材料力学性能的影响。结果表明：当强性层中的混料摩尔比为Ti∶C=1.1时，烧结温度不易控制；当混料摩尔比为Ti∶C=1.2,烧结温度为1100℃时，制备出的Ti-TiC/Ti层状复合材料组织均匀，层状结构保持良好，抗弯强度性能最佳，达到819.8 MPa,且强性层中的硬度分布均匀。烧结温度为1150℃时，复合材料的抗弯强度下降。
