实验结果表明，ATC复合材料的抗裂纹扩展能力与抗循环热震性能都优于AT，ATC的临界温差△正比AT高25℃。诸抗热震参数R、R^I、R^IV和Rst的计算结果也表明，ATC的抗热震断裂能力和抗热震损伤能力均高于AT。

The results under the oil lubricate friction conditions were similar with those under the dry friction conditions. The wear mechanism of 3Cr13 matrix alloy was micro-cutting and distorting wear. For the composites with a low fraction of TiC particle, distorting wear dominated and cutting was partly operating. For the composites with a high fraction of TiC particle, stress fatigue wear and wear of hard phase decohesion has occurred, but the main wear mechanism was still distorting wear. When the wear experiments were performed under the oil lubricate friction conditions, the main wear mechanism has became to abrasive wear and fatigue wear for the composites with the low TiC fraction, and fatigue wear would be to dominate for the composites with the high TiC fraction. There were similar wear mechanisms in H13 and 1Cr18Ni9 matrix composites.

在干摩擦条件下，3Cr13基体合金的磨损机理为显微切削和变形磨损；低体积分数的复合材料磨损机制以变形磨损为主，兼有少量的切削磨损机制；高体积分数的复合材料磨损机制以变形磨损为主，兼有应力疲劳磨损和脆性相剥落磨损；在油润滑摩擦条件下，3Cr13基体合金的磨损以磨粒磨损为主；低体积分数的复合材料磨损为磨粒磨损和疲劳磨损；高体积分数的复合材料磨损以疲劳磨损为主。H13、1Cr18Ni9基体及其复合材料的磨损机制类似于3Cr13基体及其相同体积分数的复合材料。

结果表明，在5种不同球磨环境下用Ti粉和活性炭粉都能合成TiC，其中在H2环境下的合成速度最快。H2对TiC的机械合金化合成具有加速作用，其机理是H2不仅能促使Ti与活性炭粉末细化，使断裂的新鲜表面保持清洁，而且能使Ti的活性增强。
