Hadfield Steel Work Hardening Effect
The manganese hard steel work-hardening effect increases the surface hardness of austenitic manganese steels through mechanical stress, forming a wear-resistant edge layer.
Physical-Chemical Mechanism of Action
Mechanical impact or pressure loading on austenitic manganese steels leads to dislocation pile-up and stacking fault formation. This changes the crystalline structure of the surface, increases its hardness, and improves its wear resistance.
Metallurgical Relevance & Welding Risks
The effect can lead to a hardened surface layer that may complicate welding. Improper handling or excessive loading can cause surface cracks or wear issues.
Workshop Practice & Instructions
When machining manganese steels with a work-hardening effect, use careful mechanical procedures. Keep the loading under control and aim for a finely polished surface to facilitate welding.
