تأثير التلدين على نسبة السحب المحددة للصلب ثنائي الطور في عملية السحب العميق

Abstract EN

In this paper it have been studied the effect of annealing on the limiting drawing ratio for dual phase steel in deep drawing.

Through the experimental practice many specimens were cut to the rectangle shape with dimensions close to the desire blank diameter, then these specimens formed to the final diameter by turning machine.

The blanks put in a furnace, then the temperature increases until the critical annealing region (DJ), then it leaves in a furnace to cooling slowly to room temperature.

The mechanical properties like yield stress, tensile strength, and the limit drawing ratio before and after annealing were measured.
