| Abstract Scope |
Bulk metallic glasses (BMGs) exhibit unique characteristics and may offer superior performance compared to conventional alloys, however; today’s BMGs are of limited industrial relevance due to thickness limitations intrinsic to traditional manufacturing methods. With Additive Manufacturing (AM), a unique capability to manufacture BMGs has become available as it combines the required cooling rates and exceeds the build limitations associated to traditional methods. While AM processing has been demonstrated in Zr-based BMGs, Fe-based alloys show limited printability as they suffer from cracking and porosity in the final build, preventing use in industrial applications. Integrated Computational Materials Engineering (ICME) is a key to understand the process-structure-property evolution within AM-builds mitigating the trade-off between printability and vitrification. An ICME-based modelling approach is used to design novel Fe-based BMGs tailored to harness AM specific opportunities and to overcome associated challenges. |
