Results obtained in the present project are summarized as follows ;1.Fiber-reinforced MMC : Creep damage in an SiC-whisker reinforced Al allpy was numerically simulated by using a unit cell model. The creep damage was revealed to initiate at the edge of whisker, from which a subsequent debonding developed. An FEM code was established for quenching process of MMC.The formation of voids and progress of damage initiated from voids were found to occur along the inteface.2.Particle-dispersed MMC : Alminum dispersed with SiC particles was processed by a centrifugal casting method. The effect of casting condition on the radial distribution of particles was clarified experimentally. A FEM code for elastic-viscoplastic strees analysis was constructed based on the solidification of molten matrix considering the particle motion. The validity of the code was confirmed by experimental results.3.Surface-modified MMC : A FEM code was proposed by modeling the detonation-coating process of ceramics on a metal surface. A large tensile stress was found to occur in coated layr. The equivalent stress of Mises type may control the failure of detonation-coated layr in an alumina-coated stainless steel under biaxial loading. Structural analysis using a molecular dynamics procedure developed for sputtering process suggested that an anchor effect was the main mechanism of interface bonding.

在本项目中获得的结果总结如下：1。Fiber-Reforced MMC：SIC-Whisker强化的Al allpy中的蠕变损伤通过使用单位细胞模型在数值上模拟。揭示了蠕变损伤是在晶须边缘发起的，随后从中产生了脱芯。建立了一种用于MMC淬灭过程的FEM代码。发现空隙的形成和从空隙引发的损害的进展。实验阐明了铸造条件对颗粒径向分布的影响。基于考虑颗粒运动的熔融基质的凝固，构建了用于弹性粘膜弹性弹性弹性弹性弹性弹性弹性弹性弹性弹性弹性的代码。该代码的有效性通过实验结果证实。3。截面修饰的MMC：通过对金属表面上的陶瓷的爆炸涂层过程进行建模，提出了FEM代码。发现在涂层的Layr中发现了巨大的拉伸应力。 MISES类型的等效应力可以控制双轴负荷下氧化铝涂层的不锈钢中爆炸涂层的失败。使用用于溅射过程开发的分子动力学程序的结构分析表明，锚定效应是界面键合的主要机制。
