Formabilità a caldo di lamiere in acciaio altoresistenziale 22MnB5 a spessore ridotto

The thesis work has involved the study of the hot formability of high strength steel sheets 22MnB5 reduced thickness, which is used in the industrial process hot stamping.\nOnce the execution of formability tests using the prototype of the University of Padua, and processed images acquired during the forming process, we have evaluated the parameters of deformation prior to failure in the instant that form the basis for the construction of curves formability limit FLC
