In this study. we investigate the impact of prior ferrite on the bainite transformation kinetics and microstructure of medium-carbon steel interrupted by an intercritical annealing (IAA) process. It was found that the incubation time and completion time decreased from 687 s and 6018 s to 20 s and 4680 s. with the volume fraction of ferrite increasing from 9. https://ashleyshomestores.shop/product-category/5-piece-pub-set/
