Abstract

resumo da patente de invenção para: "método de produção de um produto de aço plano com uma microestrutura amorfa, parcialmente amorfa ou cristalina fina e produto de aço plano com tais características". a invenção proporciona métodos para produzir uma tira de aço grossa de 0,8-4,5 mm, com uma microestrutura amorfa, parcialmente amorfa ou cristalina fina com um tamanho de grão na faixa de 10 – 10 000 nm, e também um produto de aço plano com características correspondentes. de acordo com a invenção, para este efeito, um aço fundido é moldado por vazamento em um tira de aço vazada (b), em um dispositivo de vazamento (2), e é arrefecido a uma velocidade acelerada. juntamente com o fe e impurezas que são inevitáveis por razões de produção, o material fundido contém pelo menos dois outros elementos do grupo constituído por “si, b, c e p”. neste caso, aplica-se o seguinte ao teor desses elementos (em % em peso) si: 1,2 - 7,0%, b: 0,4 - 4,0%, c: 0,5 – 4,0%, p: 1,5 – 8,0%. com uma composição correspondente e uma microestrutura com características correspondentes, um produto de aço plano de acordo com a invenção tem uma dureza hv0.5 de 760-900.
