Achieving strength-ductility and functional integration is a key issue to promote the application of alloys in field materials. CoFeNiCrxAl1−x exhibit excellent magnetic corrosion resistance properties; however, their mechanical properties remain underexplored insufficiently understood. In this work, microstructure were investigated, intrinsic deformation mechanisms elucidated. The results indicate that as Cr gradually replaced by Al, phase structure transforms from single-phase face-centered cubic (FCC) dual-phase FCC body-centered (BCC), finally BCC/B2 structure. Mechanical tests demonstrated alloy hardness rises with higher Al content, Cr0Al1 exhibiting approximately 3.3 times greater than Cr1Al0 alloy. Notably, Cr0.5Al0.5 exhibits an optimal balance, yield strength increase about 60% 248 MPa tensile 36% 610 MPa, while maintaining nearly same ductility found be driven solid solution strengthening due severe lattice distortion, high dislocation density resulting reduced formation energy, second-phase interface via micrometer-scale BCC phase, twin-induced plasticity induced stack fault energy. This work broadens potential applications CoFeNiCrxAl1-x versatile engineering
