  "abstract": "Laser powder bed fusion of the hypo-eutectic eutectic alloy Al 0.75 CrFeNi 2.1 conveniently produces an ultrafine quasi-lamellar microstructure composed of fcc and bcc phases. This is achieved by annealing the as-built and almost fully fcc microstructure, which has been published previously. In this study, two different annealing treatments were carried out, i.e. at 900 °C and 1000 °C for 6 h. The samples were compressed at temperatures up to 800 °C using in-situ high energy synchrotron X-ray diffraction (HEXRD). This technique provides studying macroscopic and phase-specific stress-strain evolution and therefore more insight into the stress partitioning as a function of test temperature between fcc A1 and bcc ordered B2. This analysis shows that below 400°C B2 is the major contributor to hardening, while above 600°C A1 contributes more, suggesting the softening of B2. The ultra-fine quasi-lamellar structure with confined B2 lamellae induces remarkably high dislocation density and hardening, as well as co-deformation of both phases. The dislocation density evolution was used to describe the macroscopic flow stress-strain using a phase fraction-weighted Taylor equation. The temperature capability of the novel material was compared with established materials and bridges the gap between steels and Ni-based alloys for applications up to 650 °C.",
