X-ray diffraction and magnetic analysis of deformation induced martensites in a Fe-17Mn-1.9Al-0.1C steel

摘要

The deformation induced martensitic transformations in a Fe-17Mn-1.9Al-0.1C steel are investigated by X-ray diffraction and magnetic measurements. Martensites α′ and ∈ are formed at the same time during cold deformation of the steel. The starting (A s) and final (A f) temperatures of the reversion of martensite α′ during continuous heating are 390°C and 540°C. The martensite ∈ seems to be reverted in the 300°C–450°C range. These results are discussed and compared with those previously obtained in conventional stainless steels.
