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.

主要研究成果从新合金的制造、应用/实际应用/工业化和计算机科学方面描述如下。在新合金方面，我们制造了具有良好成形性和软磁性能的新型钴基合金，其机械强度达到5200 Mpa，创世界纪录，是传统合金的两倍左右。我们还制作了重量为4.5 Mg/m3的Ti-Fe二元合金和最大直径为12 mm的新型Ni60Pd20P17B3合金。在应用/实际应用/工业化方面，我们成功地制造了金属玻璃微减速电机。该微型减速电机是由直径为1.9毫米的塑料制成的，其尺寸比实际使用的传统减速电机要小。此外，我们还开发了由金属玻璃制成的小型压力传感器。在计算机科学方面，我们建立了成分计算系统…More ia，可用于测定大块金属玻璃的合金成分。更准确地说，我们假设子群（s, dEf， dLp和p）和早期(E)和晚期(L)过渡金属为元素周期表中的组成元素，我们创建了四面体形状的组成图。结果表明，块状金属玻璃的组成在四面体组成图上形成了一个组成带，并提出了一种新的分子动力学模拟方法。例如，我们发现在C6Cf23化合物中允许假想簇的随机旋转发生结构转变，随后发生结构弛豫。这些主要研究成果都是新颖的、具有独创性的成果。特别是在新型合金的制备、应用/实用化/产业化方面的研究成果被评为“世界第一”，在产业界和学术界产生了重大影响。少
