项目摘要

Principal research achievements are described below in terms of fabrications of new alloys, application/practical usage/industrialization and computer science. As far as the new alloys, we have fabricated new Co-based alloy with good formability and soft magnetic properties, and with mechanical strength of 5200 Mpa, which is the world record and is approximately two times greater than that of the conventional alloys. We also have fabricated a Ti-Fe binary alloy with a gravity of 4.5 Mg/m3 and new Ni60Pd20P17B3 alloy with a maximum diameter of 12 mm. As for the application/practical usage//industrialization, we have succeeded fabricating micro geared motor of metallic glasses. The micro geared motor has been fabricated smaller than the conventional one used as a practical level, which is made of plastics with a diameter of 1.9 mm. Furthermore, we have developed small pressure sensors, which are made of metallic glasses. As for the computer science, we have established composition criter … More ia, which can be used to determine the alloy compositions for the bulk metallic glasses. More precisely, we supposed sub-groups (s, dEf, dLp and p) and early- (E) and late -(L) transition metals for constituent elements from the periodic table, and we created the composition diagram in a shape of tetrahedron. As a result, we confirmed that compositions of bulk metallic glasses form a composition band on the tetrahedral composition diagram, In addition, we have proposed a new molecular dynamics simulation method. For instance, we revealed that a structural transformation takes place by allowing random rotations of hypothetical clusters in C6Cf23 compound, followed by their structural relaxations. These principal research achievements are new and novel results with originality. In particular, research results in terms of fabrications of new alloys, application/practical usage/industrialization, which are evaluated as "World No.1", have given an large impact to industry and academic fields.

主要研究成果如下：新型合金的制备、应用/实用化/工业化和计算机科学。在新型合金方面，我们制备了具有良好成形性、软磁性能和力学性能的新型钴基合金。强度达到 5200 Mpa，这是世界纪录，大约是传统合金的两倍。我们还制造了比重为 4.5 Mg/m3 的 Ti-Fe 二元合金和新型合金。 Ni60Pd20P17B3合金的最大直径为12毫米至于应用/实用化//工业化，我们已成功制造出金属玻璃的微型齿轮电机，该微型齿轮电机已被制造为比传统的实用级更小。它是由直径为1.9毫米的塑料制成的。此外，我们还开发了由金属玻璃制成的小型压力传感器。至于计算机科学，我们已经建立了成分标准。 … 更多 ia，可用于确定块状金属玻璃的合金成分。更准确地说，我们假设有子族（s、dEf、dLp 和 p）以及早过渡金属 (E) 和晚过渡金属 (L)。根据元素周期表中的组成元素，我们创建了四面体形状的成分图。结果，我们确认了大块金属玻璃的成分在四面体成分图上形成了成分带。此外，我们还提出了一种新的成分带。例如，我们揭示了C6Cf23化合物中假设的团簇发生随机旋转而发生结构弛豫，这些主要研究成果是新颖且具有独创性的研究成果。在新型合金的制备、应用/实用化/产业化方面被评为“世界第一”，在工业界和学术界产生了较大影响。
