摘要：

This paper reports a cost-effective Fe40Cr40Ni20 40 Cr 40 Ni 20 (at%) dual-phase multi-principal element alloy with excellent cryogenic mechanical properties. The high strength primarily originated from an ideal fully constrained heterostructure, which enhanced back stress strengthening and dislocation strengthening. Twinning enhanced the deformability and the strength of the alloy simultaneously.
