Patterns of the combined process of reduction–mandrelling

Specific provisions on the regularities of the combined reduction-mandreling process are refined. The results of new experiments for a detailed study of the combined reduction-reduction process are presented. Comparison of these results with theoretical predictions is confirmed the high accuracy and reliability of the calculation formulas. The results of analysis allow making a number of new insights that are useful for the successful design of a combined technological process of reduction–mandrelling.
Keywords: reduction; mandrelling; bushing production; plastic deformation; strain.

Plastic deformation of metal in repair production for the restoration of hollow cylinder parts

The article shows non-traditional methods of plastic deformation of metal for restoring the internal cylindrical surfaces of hollow cylinder-type parts made of iron-carbon alloys by creating a movable temperature gradient along the axis of the part by the example of cylinder liners, as well as the possibility of restoring the outer cylindrical surfaces of «hollow cylinder» by creating a temperature gradient along the radius of the detail using the example of a piston pin of automotive tractor diesels.
Keywords: piston; cylinder liner; repairs; thermoplastic deformation; heat; thermocooled matrix.
