摘要：
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.
