Abstract

Intensity of structural changes during forging is usually determined in dependence on the forging ratio. Forging ratio at elongation is most often calculated with use of simple relations, which are based on the change of crosssection of the forged pieces. The intensity of structure development is influenced not only by the simple change of crosssections, but also by relative length of the stroke, magnitude of deformation in individual passes, manner of edging, temperature, friction and shape of anvils. The paper gives an analysis of influence of the relative length of the stroke on the forging ratio.

Keywords: forging, relative length of the stroke, forging ratio
