The R-curve and thermal shock resistance properties are improved and the transformation effect are strengthened by the surface compressive stress effect.
表面压应力作用强化了相变增韧效果，改善了材料的表面抗裂纹性能和抗热震稳定性等力学性能。
The experimental result coincided with the thermal shock parameter R and R calculated values based on thermal shock fracture and thermal shock damage.
这同热震断裂和热震损伤理论计算的热震参数R和R的结果相一致。
