A strategy was developed to circumvent the trade-off between the yield strength and strain hardening capability in Fe–30Mn–11Al-1.2C low-density steel by coupling two-step aging and intermediate pre-strain processes. The improvement of strain hardening capability is attributed to the non-shearable intragranular DO3 particles.

晶内脆性沉淀物改善了Fe-30Mn-11Al-1.2C低密度钢的应变硬化能力
通过结合两步时效和中间预应变工艺，制定了一种策略来避免在Fe-30Mn-11Al-1.2C低密度钢中屈服强度与应变硬化能力之间的取舍。应变硬化能力的提高归因于不可剪切的颗粒内DO 3颗粒。
