This study was carried out to develop new composite materials which show characteristic properties in both microscopic and macroscopic levels focusing on the high pressure effect to the materials. The composites in this study is defined more broader sense containing amorphous hydroxide compounds prepared at high pressure which forming a microscopic composite by doping water into the structure at high pressure. When high pressure stable diamond or cubic BN particles were dispersed in the matrix, we can prepare macro-composite.Micro-composite studied were Sr-Cu-O and La-Sr-Cu-O compounds. These compounds showed high pressure phase transformation and only oxygen doped high pressure phases showed superconductivity. We studied pressure, temperature and composition relationship and doping effect of oxygen to realize superconducting state.Diamond and cBN dispersed sintered composite were studied as macro-composite. Evaluation as cutting tool performance was carried out using hardened tool steel work. New TiC dispersed diamond composite was developed.

进行了这项研究以开发新的复合材料，这些材料在显微镜和宏观水平上均显示出侧重于对材料的高压效应的特征。这项研究中的复合材料被定义为更广泛的意义，其中包含在高压下制备的无定形氢氧化物化合物，该化合物通过在高压下将水掺入结构中形成微观复合材料。当高压稳定的钻石或立方BN颗粒分散在基质中时，我们可以准备宏观复合材料。研究的微复合材料是SR-CU-O和LA-SR-CU-O化合物。这些化合物显示出高压相变，只有氧气掺杂的高压相显示超导性。我们研究了氧气的压力，温度和组成关系以及掺杂效应以实现超导状态。二叉树和CBN分散的烧结复合材料被研究为宏复合材料。使用硬化工具钢处理进行评估作为切割工具性能。开发了新的TIC分散钻石复合材料。
