Abstract

Martensitic transformation behavior of austenite during cooling was investigated. Tensile tests were conducted on specimens whose retained austenite was changed from the as-annealed level (9. 5%) to a reduced value (3%) by cooling down to 77 K under a high magnetic field (222. 4 kOe). Retained austenite lowers the flow stress in the smaller strain region and increases the work-hardening rate in the larger strain region up to necking during plastic deformation. This results in an improvement in ductility.
