In-situ Observation of Martensite Transformation and Retained Austenite in Supermartensitic Steel

摘要

Martensite transformation of Supermartensitic steel during weldingrncycle was in-situ observed by using high temperature laser scanningrnconfocal microscopy and X-ray diffraction by Synchrotron radiation.rnFrom the test results, X-ray diffraction integration strength of austeniternwas increased by the influence of the martensite transformation stress.
