摘要

The precipitates formed in a new series of [Formula presented] maraging steels when aged at 500 °C were identified as the L2₁-ordered Ni₂TiAl phase. The precipitate formed a coherent-coplanar microstructure analogously to γ/γ' Ni-based superalloys and maintained a high number density and homogeneous dispersion within α′-martensite matrix even after aging for 10,080 min. An increase in the Mn content of the alloy led to faster precipitation kinetics and thus rapid hardening kinetics.
