转变上的 austempering 的效果导致了热卷的多相的钢的粘性(旅行) 被调查。多角形的铁酸盐,小粒的巴菌体,和大量稳定的保留的奥氏体能在热卷的多相的钢被获得。有效地拉紧保留的奥氏体和旅行的导致的马氏体转变(SIMT ) 发生在在在 400 ° C 的为 austempering 的在相对高的经常的价值的热滚动,和现在的钢遗体的机械性质以后由于 austempering 拉紧下面。因为当钢为 20min 被保持时,保留的奥氏体的稳定性是最佳的,钢的机械性质展出了张力的力量(791MPa ) 和全部的延伸(36%) 的好联合。
Effect of austempering on the transformation induced plasticity (TRIP) of hot rolled multiphase steel was investigated. Polygonal ferrite, granular bainite, and a large amount of stabilized retained austenite could be obtained in the hot rolled multiphase steel. Strain induced martensite transformation (SIMT) of retained austenite and TRIP effectively occur under straining owing to austempering after hot rolling, and mechanical properties of the present steel remain at a relatively high constant value for austempering at 400℃. The mechanical properties of the steel exhibited a good combination of tensile strength (791MPa) and total elongation (36%) because the stability of retained austenite is optimal when the steel is held for 20min.
