Abstract

resumo patente de invenção: "aço de alta resistência que exibe boa ductilidade e método de produção por meio de tratamento de têmpera e partição através de banho de zinco". a presente invenção refere-se à produção de um aço com alta resistência e boa maleabilidade com composições e métodos para formar microestrutura de austenítico e de martensítico no aço. carbono, manganês, molibdênio, cobre de níquel e cromo podem promover a formação de austenita estável à temperatura ambiente (ou metaestável) através de mecanismos, tais como a redução de temperatura de transformação para constituintes de não martensítico, e/ou aumento da rigidez do aço. os ciclos térmicos que utilizam um resfriamento rápido abaixo de uma temperatura inicial de martensita seguido por um reaquecimento podem promover a formação de austenita à temperatura ambiente estável através da permissão de difusão de carbono em austenita a partir de martensita.
