It was found thatthe secondary hardening effect and resistance to heat softening as well as impacttoughness are higher in the bainite than in the martensite. TEM observations showthat the Fe_3C precipitated in the martensite after temrering at the temperaturenear the peak of hardening-tempering temperature curve. However, no Fe_3C but thedispersive MC and M_2C precipitated in the ferrite and austenite of bainite aftertempering at the same temperature. This shows the diffusion of alloy elements form-ing carbide must be taken during the process of bainite growing.
