TEM observation on precipitates in low carbon high strength steels produced by EAF-CSP process

摘要

Compact Strip Production(CSP)is a new proncess for production of hot strips from continuously casting nthin slabs by direct charging.The hot strips produced nby CSP process undergo different thermo-mechanical nprocess compared with the conventional cold charging nprocess.Supersaturation of microalloy elements in the nsolid solutions is obvious higher than that in the strips nproduced by conventional process[1].Thus, detail study non the precipitation for the direct charging process is nrequired in order to improve microstructure and propernties of the steels.
