Developments in Cryodeformation: Upsetting under All-Round Compression

The new method of cryodeformation under all-around compression conditions is described. The impossibility of existing technologies to increase the efficiency of combined treatment of low-plasticity materials (in particular, the “upsetting-extrusion” method) by temperature treatment decreasing to the cryogenic region are considered. The technical possibility of such cryodeformation is discussed. The construction and operation principle of the developed device is described. The treatment efficiency of low-plasticity materials by this device on the example of technical magnesium and titanium nickelide alloy is shown. The need to clarify the formulations used to designate the methods of metals cryodeformation under conditions of all-round compression is discussed.
