The precipitation behaviors of (Ti, Nb, Mo)C in specimens of Ti-Nb-Mo steel hold at 700°C under no deformation condition and deformation condition with engineering strain 0.4 imposed in austenite region have been studied. The results indicate: under no deformation condition, the rows of interphase precipitation show straight and/or curve morphology, and the precipitation behaviors include interphase precipitation, random precipitation and fibrous precipitation; under deformation condition, the rows of interphase precipitation are straight, and the precipitation behaviors include interphase precipitation and strain-induced precipitation. Furthermore, the dispersion of precipitate particles formed under deformation condition is more uniform than those formed under no deformation condition.
