由预合金和混合粉末制造的粉末冶金双相奥氏体－铁素体不锈钢双相奥氏体－铁素体不锈钢由于其性能兼于纯铁索体钢和奥氏体钢之间所以用途越来越广泛。但是，从制造观点来看，双相钢的困难主要是由于要求精确控制化学成分以及在成形热处理时需要严格控制温度。这些困难的存... Powder metallurgy duplex austenitic-ferritic stainless steels made of prealloyed and mixed powders Duplex austenitic-ferritic stainless steels are used more and more because of their properties as between pure ferritic and austenitic steels The more extensive. However, from a manufacturing point of view, the difficulty of dual phase steels is mainly due to the need for precise control of the chemical composition and the need for tight temperature control during the forming heat treatment. These difficult deposits ...
