| Abstract: | The chemical composition,diameter and shape factor of fine particle in the precipitated phase of the control rolled and acceleratedly cooled Mn-Nb-RE steel were measured;influences of controlled rolling and accelerated cooling rates on diameter,shape factor of fine particle and increment of yield strength and relationship between increment of yield strength of control rolled and acceleratedly cooled Nb-bearing steel and average diameter of the fine particle were analyzed;and mechanism of precipitation hardening of the fine particle discussed. |

| Keywords: | controlled rolling accelerated cooling fine particle precipitated hardening |
