摘要: 分析了强塑性组合极好的相变塑性钢在应用的广泛性方面,反而远不及强塑性不如它的双相钢的原因.参照热力学和动力学计算结果,研制了可热镀锌并具有良好焊接性的相变塑性钢,并得到试验和生产证实.为了适应国内钢厂生产,提出以磷代硅以提高钢的可镀性方法,从而代替代了国外以铝代硅的方法.

Abstract: TRIP steel is less popular in automobile industry as compared with DP steel although the latter has much lower strength and ductility. Reasons for this are listed. By careful calculation based on thermodynamics and kinetics, a new type of TRIP steel with good weldability and galvanizing property is successfully developed both in the university laboratory and on a modern production line of steel plant. In order to make the steel suitable for domestic metallurgy processing, phosphorus is used to substitute silicon instead of aluminum.

Key words: galvanizing property, kinetics, thermodynamics, weldability, TRIP steel
