Bogatov A.A., Nukhov D.Sh. Development of a method of blacksmith stretching without changing the shape and dimensions of the billet

Abstract

The article deals with alternating deformation during cast-ingots stretching without changing original shape and sizes. The method involves usage of forging dies [1] with two faces which are smooth and profiled. The authors have determined rational engraving of the profiled die face and reduction conditions which provide high uniform deformation throughout the workpiece volume following the stretching.

Keywords

Cast structure; alternating deformation; degree of dispersion; math modeling; stress-strain states; stressed state parameters; the degree of shear strain; ingot stretching; stamp; reduction of a workpiece.
