... of a workpiece in the form of a cast preform. For the calculations, it has been assumed that the billet material will be a Ø30 × 148 mm rod and a cast preform. Two variants of preforms have been modeled, from which products of the assumed geometry with different degree of strain are obtained. Calculations were...
