осадка(Уменьшение высоты заготовки при увеличения площади ее поперечного сечения. ГОСТ 18970-84 // Upsetting of metals is a deformation process in which a (usually round) billet is compressed between two dies in a press or a hammer. This operation reduces the height of a part while increasing its diameter. The process is mostly used as an intermediate step in multiple step forging operations. DRE)
