| 摘 要： | 对ＰＳＺ－Ｍｏ系梯度功能材料（ｆｕｎｃｔｉｏｎａｌｌｙｇｒａｄｉｅｎｔｍａｔｅｒｉａｌｓ简称ＦＧＭ）在制备过程中的热应力缓和性能进行了优化设计，用有限元方法解析了ＰＳＺ－Ｍｏ系两层叠层材料（即非梯度功能材料）在制备过程中的热应力分布情况。同时解析了ＰＳＺ－Ｍｏ系ＦＧＭ在制备过程中的热应力分布及缓和规律。揭示了ＰＳＺ－Ｍｏ系ＦＧＭ在制备过程中的热应力大小与组成分布形状指数Ｐ的关系，对所研究的体系通过热应力解析，得到制备中热应力缓和最佳时的Ｐ值，同时，对ＦＧＭ的制备工艺进行了研究，用粉末法分别制备出２４ｍｍ×５．６ｍｍ和３０ｍｍ×５ｍｍ完整的ＦＧＭ试样。

| Abstract: | The thermal stress relaxation of PSZ-Mo functionally gradient material(FGM)during the fabri-cation process is optimally designed.By means of the finite-element method,the thermal stress distribution in a layered material of PSZ-Mo(i.e, non FGM)with two layers and that in a PSZ-Mo FGM during the fabrication process are analysed. The relationship between the thermal stress and compositional distribution exponent P for PSZ-Mo FGM during the fabrication process is obtained.The optimal value of P for the PSZ-Mo FGM un-der study is also obtained.PSZ-Mo FGMs,24mm in diameter,5.6mm thick and 30mm in diameter,5.0mmthick respectively are fabricated via a powder metallurgical method. |
