  • The effects of tempering holding time at 700 ℃ on the morphology, mechanical properties, and behavior of nanoparticles in Ti-Mo ferritic steel with different Mo contents were analyzed using scanning electron microscopy and transmission electron microscopy. Equilibrium solid solution amount of Mo, Ti, and C in ferrite at various temperature were calculated. The variation in the sizes of nanoparticles with time at different Mo contents was analyzed. The experiments and calculations were in good agreement with one other, which showed that the change in the nanoparticle size of MNF steel was the smallest during the aging process. Higher Mo contents inhibited the maturation and growth of nanoparticles, but when the Mo content exceeded 0.37 wt%, no obvious inhibition effect was observed. The tensile strength and yield strength decreased continuously with the tempering time. The analysis of the strengthening and toughening mechanism showed that the different mechanical properties between the three was mainly determined by the grain refinement strengthening (the difference range was 30-40 MPa) and precipitation strengthening (the difference range was 78-127 MPa). MNF steel with an ideal chemical ratio had the highest thermodynamic stability, and LNF and HNF have relatively similar thermodynamic stabilities.

Abstract: The effects of tempering holding time at 700 ℃ on the morphology, mechanical properties, and behavior of nanoparticles in Ti-Mo ferritic steel with different Mo contents were analyzed using scanning electron microscopy and transmission electron microscopy. Equilibrium solid solution amount of Mo, Ti, and C in ferrite at various temperature were calculated. The variation in the sizes of nanoparticles with time at different Mo contents was analyzed. The experiments and calculations were in good agreement with one other, which showed that the change in the nanoparticle size of MNF steel was the smallest during the aging process. Higher Mo contents inhibited the maturation and growth of nanoparticles, but when the Mo content exceeded 0.37 wt%, no obvious inhibition effect was observed. The tensile strength and yield strength decreased continuously with the tempering time. The analysis of the strengthening and toughening mechanism showed that the different mechanical properties between the three was mainly determined by the grain refinement strengthening (the difference range was 30-40 MPa) and precipitation strengthening (the difference range was 78-127 MPa). MNF steel with an ideal chemical ratio had the highest thermodynamic stability, and LNF and HNF have relatively similar thermodynamic stabilities.
