PCT No. PCT/PL95/00006 Sec. 371 Date Jan. 30, 1996 Sec. 102(e) Date Jan. 30, 1996 PCT Filed Apr. 7, 1996 PCT Pub. No. WO95/32818 PCT Pub. Date Dec. 7, 1995An improvement to a method for plastic forming of a material by rolling, forging or extrusion, by using a tool to exert a force on the material to obtain a product of desired geometry. The improvement comprises inducing in the material a reversible plastic strain in the form of shear bands localized in a zone of most intense deformation by the tool, by introducing a motion of the tool additional to a tool working motion which produces the desired geometry. The additional motion is reversible and transfers motion to the material due to intimate contact between the material and the tool. |
