Abstract Scope

Refractory multi-principal element alloys (RMPEAs) with BCC/B2 phase microstructures are a promising field of study with microstructure akin to γ/γ’ Ni-based super alloys while maintaining strength at higher temperatures. Despite their promise, the deformation mechanisms of BCC/B2 RMPEAs are only just beginning to be characterized, as seen in recent work on Al_0.5NbTa_0.8Ti_0.5 V_0.2Zr [1]. In this work, the deformation mechanisms and microstructural evolution of a model BCC/B2 alloy in the Fe-Al-Ni system are characterized via diffraction contrast and high-resolution STEM techniques. The BCC/B2 Fe-Al-Ni system’s microstructure is highly tailorable, which is an ideal characteristic for analysis of dislocation transmission between BCC and B2 phases. The obtained results for this Fe-Al-Ni model system are then compared to existing BCC/B2 RMPEAs [1] assisting in their optimization and future development. [1] Couzinie, Heczko, Mazanova, et al.
