РЕЖИМ ПЛОСКОЙ ДЕФОРМАЦИИ ПРИ ДЕФОРМИРУЮЩЕМ ПРОТЯГИВАНИИ ТРУБЧАТЫХ ИЗДЕЛИЙ БОЛЬШОЙ ДЛИНЫ

Abstract

The paper concerns to specific conditions of the two-dimensional local state of strain at burnishing. First time a photograph is represented which testifies to the absence of an excessive wave of metal belt in front of the burnishing tool deforming edge at such a regime. The methods of determining rates of stain across the wall thickness of a tube object are offered. Also microphotographs of a structure of the metal at the nearest neighborhood to the burnishing tool are presented.
