High-Mn steels are widely used in various fields. However, the FCC structure is not conducive to improving strength, limiting their development and application. In this work, hot-rolled Fe-25Mn-1Al-3Si-1C (wt.

This work produced two (CoCrNi)AlTiC medium-entropy alloys with exceptional strength-ductility combinations, via short/medium (3 min/30 min) annealing times after hot-rolling. Three types of intergranular precipitates including MC, MC carbides, and L1 phase were detected in both samples.

- Steel designs with enhanced mechanical properties are crucial in the automotive industry for energy efficiency, safety, and weight reduction.
- This study explores the aging process to improve yield strength through V-rich precipitate distribution and ductility via recrystallized ferrite in cold-rolled medium-Mn steel.
- The findings show that aging at 650 °C for 10 hours achieved a remarkable ultimate tensile strength of 1306 MPa and tensile elongation of 42%, outperforming existing medium-Mn steels.
