在机器和机床制造业中球铁(?)得到广泛的应用。但是,对于在交变载荷条件下工作的零件,它的应用因疲劳极限低而受到限制。经试验表明,球铁用感应加热进行热处理,可以显著提高疲劳极限。
Ductile iron (?) Is widely used in machine and machine tool manufacturing. However, its application is limited by the low fatigue limit for parts that operate under alternating loads. The tests show that ductile iron with induction heating for heat treatment, can significantly improve the fatigue limit.
