开发了一种添加 Cr (18%)、Ni (5%)、V (1%) 和 N (0.3%) 的新型中锰 (MMn) 钢，以提供增强的耐腐蚀性以及优异的强度-延展性平衡。将实验室熔炼的钢锭进行热轧、冷轧，最后在 1000 摄氏度下退火 3 分钟。再结晶单相奥氏体显微组织由超细晶粒（类似于 1.3 μm）和大量 Cr 基和 V 基析出物组成，呈双峰粒度分布（100-400 nm 和
A novel medium manganese (MMn) steel with additions of Cr (18%), Ni (5%), V (1%), and N (0.3%) was developed in order to provide an enhanced corrosion resistance along with a superior strength-ductility balance. The laboratory melted ingots were hot rolled, cold rolled, and finally annealed at 1000 degrees C for 3 min. The recrystallized single-phase austenitic microstructure consisted of ultrafine grains (similar to 1.3 mu m) with a substantial amount of Cr- and V-based precipitates in a bimodal particle size distribution (100-400 nm and
