奥氏体耐热钢含有一定量的易挥发性元素,由其制成的零件用于各种设备中,当这些零件在使用过程中受热或在真空状态下服役时,合金元素的挥发成为一个重要因素。钢由于加热面发生不期望的转变(例如奥氏体—铁素体转变),这将影响钢的物理化学性质。当奥氏体钢在热辐射条件下使用时,由于起皮而使其耐热性受到损害,因而改善奥氏体钢的耐热性尤为重要。作者认为要达到改善奥氏体钢耐热性的目的,一种有效的
Austenitic heat-resistant steels contain a certain amount of volatile elements. Parts made from it are used in a variety of equipment. When these parts are heated during use or when under vacuum, the alloying element volatilizes to one Key factor. Steel due to the heating surface of the unwanted changes (such as austenite - ferrite transformation), which will affect the physico-chemical properties of steel. When austenitic steels are used under heat radiation conditions, the heat resistance of austenitic steels is of particular importance due to the delaminated heat resistance. The authors believe that to achieve the purpose of improving the heat resistance of austenitic steel, an effective
