Abstract：The effect of cold rolling deformation prior to aging on the strengthening of a maraging steel was investigated. The results of experiments indicated that the net strength increment caused by aging at 510 ℃ for 3 h is almost constant, irrespective of percentage of reduction in thickness. Final strength can be expressed as σ=σ0+ΔσCR+ΔσAge,where σ0 is initial strength, and ΔσCR and ΔσAge are strengthening contribution due to cold working and aging respectively, and ΔσCR is only related to percentage of reduction in thickness. It was confirmed by electron diffraction analysis that the strengthening precipitates are Ni3(Ti,Mo) and Ni3Mo, regardless of percentage of reduction in thickness.
