Development of bulk metallic glass components for spacecraft applications using thermoplastic forming

Ever increasing demands on space, aerospace and defense applications require non-traditional approaches to materials and processing methods. Bulk metallic glasses (BMGs) are unique materials that combine properties of ultrahigh strength metals with processability of thermoplastics, which is often paired with other attractive attributes, such as high resilience, fracture toughness, hardness, and corrosion, erosion, and wear resistance. This project is focused specifically on thermoplastic forming (TPF) of BMGs that enables a wide range of geometries and functionalities in BMG products that are not possible to achieve with other materials and processing methods. The goal for Phase I is to mature and advance commercial opportunities for TPF of BMGs specifically for structural and functional space applications and, in later phases, for other areas of aerospace and defense. The scope of work includes an assessment of the overall advancement in the field of bulk metallic glasses, prioritization of applications, proving feasibility of the proposed methods, and developing a proof-of-concept for several BMG products with plans for manufacturing and insertion into spacecraft design.
