Abstract:

The work hardening of 26Kh2NGSM steel during deformation in the martensite state depending upon the degree of reduction and tempering was investigated. It was shown that the effect of work hardening and the character of the change in plasticity and viscosity depend on the method of treatment. The highest complex of properties is obtained during treatment by the method of quenching-tempering at 200 degrees - 20 percent reduction. Deformation of martensite promotes the deceleration of the processes of stress relief during final tempering. The high values of the yield point and of ultimate strength are maintained during heating up to 400 degrees C. With testing during the biaxial state of strain it was also established that treatment by the marforming process improves the properties which are characterized by the structural strength of the investigated steel. On the bases of the obtained results proposals were formulated on the possible structural processes, entering into the formation of the properties of steel during its deformation in the martensite state.
