Sheet metal Hardening at the Hydraulic Stretching

The projecting and improving of conventional as well as new unconventional forming processes are grounded on knowledge of material characteristics during forming process. The ground supposition for modelling and optimization of technological treatments and metal forming processes is detalied researching of plastic deformation nature. For projecting technologies of metal forming is the most important the knowledge of hardening curved (yield of metal). In this paper is given the presentation of hardening curved obtained by hydraulic stretching and comparison of mechanical stretching.
