A method of forming malleable, work-hardenable metastable nano-twins in an austenitic steel alloy. In short, a high purity raw material is smelted to obtain an as-cast steel alloy ingot and subjected to a homogenization and cold rolling treatment for rolling, then the homogenized and cold-rolled steel alloy ingot is subjected to a recrystallization treatment to eliminate any possible casting defects, and then the recrystallized steel alloy is cold-rolled again to form a nano-twin austenite structure. In the subsequent denaturation process of the nano twin austenitic steel, a nano martensite lamellar layer can nucleate along the twin boundary, so that an austenite/martensite nano layered structure is formed in a steel alloy, and good plasticity is shown.
一种在奥氏体钢合金中形成具延展性、可加工硬化的亚稳纳米孪晶的方法方法。简言之，熔炼高纯度原料以获得铸态钢合金锭，并对其进行均匀化和冷轧处理以轧制，再将经均匀化和冷轧的钢合金锭进行再结晶处理，以消除任何可能的铸造缺陷，接着，再次冷轧再结晶的钢合金，以形成纳米孪晶奥氏体结构。此纳米孪晶奥氏体钢在后续变性过程中，纳米马氏体片层会沿孪晶界形核，从而在钢合金中形成奥氏体/马氏体纳米层状结构，以表现出良好的塑性。
