High speed mechanical alloying process has been developed to yield non-equlibrium phase alloy, nano-structured intermetallics and their compisites with ceramics. Through our research and development during three years, we have found the following five results :1) Our developed mechanical alloying process can reduce the processing time by 1/10 to 1/100, make large yield of synthesized materials in the order of kilograms, and have wide range of flexible controllability.2) Fundamental processes to govern the high speed mechanical alloying can be investigated and discussed by a series of experiments where imposed mechanical energy, die-set temperature and atmosphere are controllable.3) Two dimensional Eulerian elasto-plastic finite element method was developed to make direct simulation of plastic deformation, flow and fracture processes of powder mixture and to claryfy the mechanism of high speed mechanical alloying theoretically.4) Controlled fracture forming process was further developed to yield SUS and/or Ni sheathed ceramic wires and fibers for fabrication of preforms in metal-matrix composite.5) Shock reacive processing from mechanically alloyed precursors should be a new, non-traditional processing to synthesize intermetallics and their composites with ceramics even in solid-phase.

高速机械合金化技术已发展到制备非平衡相合金、纳米结构金属间化合物及其陶瓷复合材料。通过三年的研发，我们发现了以下五个成果：1）我们开发的机械合金化工艺可以减少加工时间1/10到1/100，使合成材料的产量在公斤级，并具有广泛的灵活性。2）控制高速机械合金化的基本过程可以通过一系列实验进行研究和讨论，其中施加的机械能，模具设定温度和气氛是可接受的。4）进一步发展了可控断裂成形工艺，以生产SUS和/或Ni包覆的陶瓷丝和纤维，用于制备金属基复合材料的预制体; 5）机械合金化先驱体的冲击反应加工应是一种新的，非传统工艺，甚至固相合成金属间化合物及其与陶瓷的复合材料。
