| 摘 要： | 采用压痕-急冷法测试了单相3Y-ZrO2及3Y-ZrO2／Fe3Al复合材料的抗热震性能，并与急冷-强度法的测试结果进行了对比分析。试验结果表明，两种方法之间存在一致性。两种复合材料比基体的抗热震性均有较大幅度的提高。压痕-急冷法与急冷一强度法相比免去了热震后的强度测试，不同温度下热震可以采用同一试样，而后者在不同热震温差下，必须使用新的试样。

| Abstract: | The thermal shock resistance of ZrO 2(3Y) and ZrO 2(3Y)/Fe 3Al composite was studied using indentation-quench technique and the residual-strength method,respectively.Comparing the results of two methods,the same conclusion can be drawn that the thermal shock resistance of the composite is improved sisnificantly due to the addition of Fe 3Al particle into ZrO 2(3Y). The use of the same sample for a whole series of temperatures in the thermal shock experiments is the most pronounced advantage of the indentation-quench method, compared to residual-strength method where new samples have to be prepared for each temperature. |
