Precipitation Reactions in a Copper - Bearing GOES

Popis výsledku v původním jazyce

The paper deals with minor phase evolution in a Cu - bearing grain oriented electrical steel during the following production steps of the AlN + Cu industrial processing route: hot rolling of slabs, the 1st cold rolling + decarburization annealing and the 2nd cold rolling + slow laboratory heating to the temperature of primary recrystalization. Thermocalc calculations were used for prediction of the effect of copper additions on equilibrium phases in the temperature interval 450 - 850 degrees C. Minor phase evolution was studied by using transmission electron microscopy. Hot rolling was accompanied by dissolution of copper rich sulfides. Slow cooling of coils after hot rolling resulted in precipitation of Fe3C along ferrite grain boundaries. Decarburization annealing after the 1st cold rolling was accompanied by dissolution of Fe3C, re-precipitation of fine Cu2S, (Mn, Cu)S and very intensive precipitation of nitrides (AlN and Si3N4). Slow laboratory heating after the 2nd cold rolling to the onset of primary recrystallization (620 degrees C) did not cause precipitation of any other minor phase. No copper rich metallic particles (epsilon - Cu) formed during the production steps investigated. Most fine particles of inhibition phases formed during decarburization annealing. (C) 2016 The Authors. Published by Elsevier Ltd.
