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.

Features of production of band profiles for electrical purposes from copper alloys

The ways of achieving high performance characteristics of electrical profiles are shown in the article. For copper rectangular semi-solid tires are received simplifying the determination of в and improving the accuracy of surface quality evaluation after the bending test as a criterion for grain size. Hardness increase, camber reduction and absence of protrusions and scratches on the profile are get for copper-cadmium collector wedge-shaped (trapezoidal) strips. In its turn increase of electrical conductivity and stability of mechanic properties are presented for copper-silver collector strips. The article concisely presents the main stages of the work and the results obtained.
Keywords: electrotechnical profiles; copper rectangular tires; copper-cadmium and copper-silver collector wedge-shaped strips; improving the quality and reducing the labor intensity of production; optimization of the chemical composition of a copper-silver alloy.

Investigation of deformation process of bimetal using the software complex AUTOFORM

During research numerical computer modeling of extract process of an axisymmetric detail from bimetallic material (steel–an aluminum alloy) is carried out. The data on features of deformation of each layer in dependence of his arrangement concerning the tool are obtained. By the results of computer modeling the conclusion of feature of replacement single-layer steel sheet on multilayered bimetal (steel–aluminum) has been drawn.
Keywords: bimetal; axisymmetric extract; plastic deformation; computer modeling; steel and aluminum layers.
