Abstract Scope |
To strengthen Refractory Multi Principal Element Alloys at 1200°C and beyond, one strategy aims to design stable microstructures of B2 precipitates embedded within a BCC matrix, which emulates the γ-γ’ structure found in Superalloys. Here, we focus on Ru-based B2 intermetallics as one promising group of precipitates with a high thermal stability. We comprehensively explore the resulting space of alloy systems. We arc-melt a wide range of compositions and determine phase stability and mechanical performance under various thermal processing conditions. |
