摘要：
The use of ION type residual stress indicators for non-destructive inspection of residual stresses in rolling mill rolls and sleeves at different stages of their manufacture is analysed. These instruments use the magnetoelastic effect appearing in ferromagnetic materials under the action of stresses. The influence of the tempering temperature for quenched 9KhF steel and the heat treatment schedule for 9Kh and 40Kh steels on change in the magnetoelastic effect is examined.
