Strain aging austenitic steels

Conclusion

The effect of strain-aging can be used as the fundamental basis for creating high-tensile austenitic steels. In such a treatment hardening is effected by the decomposition of the hard solution owing to high density of defects accompanying the formation of segregations of contaminated atoms and the separation of particles of the excessive phases. Here the intensity of achieving a high-tensile state is determined by the stability of austenite depending directly on the amount of martensite formed during the plastic strain process. The possibility of obtaining in the strain-aging steels unstable and stable γ-phase creates the conditions for controlling their properties within a wide range and makes possible their use as high tensile and relaxation-resistant materials.
