Qian, F., Sharp, J. and Rainforth, W.M. (2016) Characterisation of L21-ordered Ni2TiAl precipitates in FeMn maraging steels. Materials Characterization, 118. pp. 199-205. ISSN 1044-5803
Abstract
The precipitates formed in a new series of Fesingle bondMn 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.
