Comparison of Magnetic Parameters of Quenched Pipe Steels with X-Ray–Evaluated Residual Macro- and Microstresses
- 18 Downloads
Residual micro- and macrostresses have been determined by X-ray diffraction analysis in 22KhG2A, 30KhMA, and 32G2 grade steels quenched and tempered from various temperatures. It is demonstrated that not only residual macrostresses need to be determined, as prescribed by existing regulatory documents, but also microstresses, which characterize the extreme values of residual stresses. The possibility of using magnetic parameters for evaluating residual micro- and macrostresses has been investigated. It has been established that coercive force, maximum magnetic permeability, and Barkhausen magnetic noise characteristics can be used as informative parameters in the evaluation of microstresses.
