this paper provides an overview on obtaining low-carbon ultra-fine grained dual-phase steels through rapid intercritical annealing of cold-rolled sheet as improved materials for automotive applications. a laboratory processing route was designed that involves cold-rolling of a tempered martensite structure followed by a second tempering step to produce a fine grained aggregate of ferrite and ca...

This paper focuses on the evolution of microstructure in a grain-oriented electrical steel (GOES) thin strip after casting. After solidification, consisted delta-ferrite. A small fraction austenite was formed during cooling two-phase region (gamma+delta). Fine Cr2CuS4 particles precipitated ferrite and along delta/gamma interfaces. Laths primary Widmanstätten (WA) nucleated directly high-angle ...
