Abstract

"PROCESSOS PARA FUSãO DE UM MATERIAL METáLICO REATIVO E DE UMA LIGA à BASE DE TITâNIO COMPREENDENDO ALUMìNIO E UM OUTRO METAL, E, APARELHO PARA FUSãO DE UM MATERIAL METáLICO REATIVO". Processo e aparelho para fusão de materiais metálicos reativos, tais como, por exemplo, ligas à base de titânio e outras ligas reativas, por meio do aquecimento por indução seletivo e seq³encial de uma pluralidade de componentes de carga de liga sólida segregados em um vaso de fusão refratário em uma maneira para efetuar a rápida fusão de topo-para-fundo que evita a reação prejudicial da fusão com o material de vaso de fusão refratário e contaminação do banho.
