Resumo: Os aglomerados de minério de ferro têm ganhado importância nos últimos anos, devido ao empobrecimento da jazidas e consequente necessidade de cominuição e concentração dos minerais de interesse. Estes aglomerados quando expostos às intempéries naturais sofrem perda de qualidade física. Este artigo investiga a aplicação de revestimentos à base Leia mais…

Abstract: To achieve the desired microstructural properties, the ongoing development and innovation in new structural steels require novel thermal processing. This study aims to improve the mechanical properties of a commercial spring carbon–silicon steel by tailoring its microstructure through a process involving quenching and partitioning (Q&P) followed by bainitic transformation.
