Ultrafast Heating Heat Treatment Effect on the Microstructure and Properties of Steels

The adoption of the ultrafast heating (UFH) process has gained much attention in last few years, as green energy and minimization CO2 emissions are main aspects contemporary metal science thermal treatment. effect treatment on carbon steels, non-oriented grain (NGO) electrical ferriticor austenitic stainless steels is reported this review. study highlights ultrarapid annealing microstructure textural evolution relation to microstructural constituents, recrystallization temperatures, its mechanical properties. A strong influence UFH was size, promoting a refinement terms both prior austenite ferrite size. Such an more evident medium–low NGO than that ferritic/austenitic steels. comparison between conventional shows slight microstructure. On other hand, increase uniform elongation due UFH. Textural analysis occurrence Goss component (which promotes magnetic properties), opposite with g-fiber. recovery step during plays important role determining features; areas higher content most suitable for nucleation component. As expected, slow promoted equiaxed grains, whereas rapid microstructures elongated grains result cold deformation.
