Effect of temperature, carbon content and crystallography on the lengthening kinetics of bainitic ferrite laths

The lengthening of bainitic ferrite laths in a model alloy containing a carbon gradient was observed in-situ using a Laser Scanning Confocal Microscope (LSCM). Results show that the observed lengthening rates increase with increasing temperature and decreasing carbon content. Crystallographic analysis was conducted by ex-situ electron backscattered diffraction to understand the relationship between growth kinetics and orientation relationships …
