Abstract

The technique of determination of rational thermal and mechanical conditions for deformation of longlength billets by equal-channel angular pressing “Conform” is described for producing of ultra fine grade structure in metals with acceptable deformational damage. Good agreement of metal damage prediction results  and physical experiment data is shown.
