Abstract
The residual stress state of shot peened steel sheets has been measured with X-ray, mechanical, and micromagnetic methods. The results show that macro- and microstresses, the work hardening depth and the homogeneity of shot peened states can be determined by the micromagnetic quantities. The procedure to get quantitative results is outlined briefly.
