Austenite formation and its decomposition control the final microstructure and performance of steel welds.This paper presents an in-situ characterization of austenite formation and its decomposition in both the fusion zone (FZ) and heat-affected zone (HAZ) of an Fe-C-Al-Mn steel using time-resolved X-ray diffraction (TRXRD) with synchrotron results for this questionHow does - martensite form in a pile up?How does - martensite form in a pile up?The -martensite forms in dislocation pile-ups where the a /61 1 2 partials are forced closer together by the applied stress.The volume of effective bcc material increases as more dislocations join the pile-up until the nucleus formed by this process reaches a critical size and rapid growth takes place.Martensite Formation - an overview ScienceDirect Topics results for this questionHow does ferrite plates grow into austenite plates?How does ferrite plates grow into austenite plates?Ferrite plates grow rapidly into the austenite.However,C diffusion is slow at the lower temperatures with the result that C saturation of ferrite occurs and carbide precipitates in the ferrite.Little C is rejected into the austenite.Martensite Formation - an overview ScienceDirect Topics
