| Abstract |
Effect of transformed ferrite content on the mechanical properies of dual-phase steels has been studied and analyzed on the basis of observation on the austenite-to-ferrite transformation behavior during post-anneal cooling. Various contents of transformed ferrite were obtained by changing intercritical annealing temperature. As the transformed ferrite content was increased up to about 40%, dual-phase properties became better due to the finer distribution of martensite particles. However, the dual-phase properties were deteriorated when the transformed ferrite content becomes larger than the retained ferrite content. The significance of these results is discussed in relation to the austinite-to-ferrite trans formation behavior during intercritical annealing. |
