AbstractVariations of the grain size and its distribution of an ultra-purified 18Ni (2200 MPa grade) maraging steel under different solution treatment temperatures (STT) have been investigated, and the relationships between prior austenite grain size and tensile properties in both solutions and aging conditions were examined, and the mechanism was also discussed. The results show that the prior austenite grain size normally and consistently increases with increase of STT. Effects of the prior austenite grain size on strength and ductility are nearly independent of STT for the maraging steel in unaged state, and the thermal brittle at high solution temperature resulting from the segregation of inclusions, such as Ti(C, N), at prior austenite grain boundary is avoided because trace elements were removed to extremely low level. However, the Hall-Petch relationship is obeyed in aged condition, and the increase in prior austenite grain size induced the segregation of precipitates on grain boundary and aging brittle.
