Abstract
aquecimento de um aço metaestável antes ou no decorrer da laminação a frio suprime a transformação de austenita em martensita, resultando em cargas de moinhos menores e em quantidades maiores de redução a cargas similares. aço laminado quando quente tem propriedades mecânicas melhoradas quando comparado com aço reduzido à mesma quantidade por laminação a frio. laminação a quente seguida por recozimento subsequente também resulta em propriedades mecânicas melhores do que aquelas conseguidas no material laminado a frio da mesma quantidade e então recozido. aço metaestável que foi laminado a quente, na laminação a temperatura ambiente subsequente (laminação a frio), também mostra melhoramento tanto na resistência quanto na ductilidade.Heating a metastable steel before or during cold rolling suppresses the transformation of austenite into martensite, resulting in smaller mill loads and larger amounts of reduction to similar loads. Hot rolled steel has improved mechanical properties compared to steel reduced by the same amount by cold rolling. Hot rolling followed by subsequent annealing also results in better mechanical properties than those achieved in cold rolled material of the same amount and then annealed. Metastable steel that has been hot-rolled at subsequent room temperature rolling (cold rolling) also shows improvement in both strength and ductility.
