Research on Fatigue Fracture Appearance of Ferritic and Pearlitic Spheroidal Graphite Cast Iron 铁素体球铁和珠光体球铁疲劳断口形貌的研究
According to the author, it is necessary to control the free manganese content, raise the temperature of molten iron and prevent molten iron from oxidizing when high sulphur ferritic malleable cast iron is produced. 因此,生产高硫铁素体可锻铸铁时,要控制好自由锰量、提高铁水温度和防止铁水氧化。
Size distribution and precipitation of VC particles in the ferritic nodular cast iron have been examined by techniques of ultrasonic screening, small angle X-ray scattering and chemical dissolution. 采用超声波筛分、X射线小角散射及化学溶解等方法,分析了铁素体球铁中VC的粒度分布和析出规律。
