Scope
This document specifies the method of detecting stress, microstructural changes, and phase transformations in carbon steel and alloy steel materials using the principles of micro-magnetism.
This document is applicable to the detection of stress distribution and its state, microstructural changes, and organizational structure changes in carbon steel, alloy steel, and austenitic stainless steel. The detection of other metal materials can be used for reference.
