摘要: 实验测量了TiC 烧结体的高温塑性变形行为, 讨论了掺入Cr3C2 对TiC 高温塑性变形的影响, 结合TiC/Ni3A l 梯度材料的循环热冲击特性得出: TiC/Ni3A l 梯度材料有效热导率随循环次数增加呈下降趋势与TiC 的塑性变形行为密切相关, TiC 表面的纵向裂纹是由巨大的径向压应力引起的。

Abstract: The high temperature ductile deformation behavior of TiC sintered body with various content of Cr3C2 addition was investigated. The results show that the descending trend of the effective conductivity of TiC/Ni3Al FGMs with the numbers of shock cycles relates closely to the ductile deformation behavior of TiC, and the vertical cracks appearing on the TiC surface is caused by large radial compressive stresses.-
