Abstract

Изобретение относится к способу изготовления детали из аустенитной легированной марганцем стали с использованием эффекта пластичности, вызванной двойникованием (TWIP эффекта). Деталь (1) деформируют так, что деталь (1) имеет практически одинаковую толщину в диапазоне 0,5-2 мм в каждой области (A, B, C, D) детали (1), при этом деталь (1) имеет по меньшей мере две области, имеющие разные значения механических свойств.
