Designing metallic glass structures for damage tolerance via 3D printing

该项目旨在在理解工艺-结构-性能关系方面取得突破性进展，这些关系支配着激光粉床熔融添加剂制造所产生的大块金属玻璃的断裂韧性。该项目旨在产生关于如何通过创造设计的玻璃微结构的新加工方法来控制大块金属玻璃的断裂韧性的新知识。预期结果将是提高开发块体金属玻璃并将其商业化的能力，使其具有优于传统金属合金的机械性能。预期收益将是航空航天、国防、交通、生物医疗设备、消费品和3D打印行业的改进产品。

This project aims to make breakthrough developments in understanding the processing-structure-property relationships that govern the fracture toughness of bulk metallic glasses produced by laser powder bed fusion additive manufacturing. The project intends to generate new knowledge on how to control fracture toughness of bulk metallic glasses via novel processing approaches that create designed glassy microstructures. Expected outcomes will be an enhanced capacity to develop and commercialise bulk metallic glasses with mechanical properties superior to conventional metal alloys. Anticipated benefits will be improved products for the aerospace, defence, transportation, biomedical device, consumer product, and 3D printing industries.
