采用温压成形和微波烧结的复合方法制备了TiC/316L不锈钢复合材料,研究了制备方法对复合材料组织与致密化的影响,并对其复合致密化机理进行了探讨.结果表明:与常规粉末冶金法相比,因为提高了压坯的生坯密度和加速烧结致密化过程的进行,采用温压成形和微波烧结的复合方法可以获得较高相对密度的复合材料试样.与常规试样的相对密度相比,采用温压成形和微波烧结制备的0％、2％、5％、10％和15％ TiC的复合材料相对密度分别由84.05％、87.12％、90.61％、89.57％和89.13％提高至92.08％、93.14％、94.83％、94.22％和93.91％,且TiC颗粒分布更均匀,减少了增强体颗粒在基体中的聚集.
