Bulk metallic glasses are a new class of superior, high-performance structural material exhibiting ultra-high strength and high corrosion and wear resistance. However, they suffer from poor ductility and the inability to strain harden, which restricts their range of applications. A recent novel approach of embedding ductile shape-memory-alloy particles into the glassy matrix is a promising way to improve ductility. The project aims to identify the optimal structures of these particles and the corresponding process for improving the properties of copper-zirconium based metallic glasses. This project is expected to create ductile metallic glass composites attractive for engineering, medical, sporting, and military applications.

块体非晶合金是一种新型的上级、高性能结构材料，具有超高强度、高耐腐蚀性和耐磨性。然而，它们的延展性较差且无法应变硬化，这限制了它们的应用范围。最近提出的一种新的方法，即在玻璃基体中嵌入韧性形状记忆合金颗粒，是一种很有前途的方法，以提高延性。该项目旨在确定这些颗粒的最佳结构和相应的工艺，以改善铜锆基金属玻璃的性能。该项目预计将创造出具有工程、医疗、体育和军事应用吸引力的韧性金属玻璃复合材料。
