One of the requirements of the modern materials market is the stable balance between the manufacturer and customer interests. However in order to improve the competitive edge the manufacturer should be able to adapt well to the changing market conditions. This feature is especially important when the manufacturer only starts producing the products with improved consumer properties. The article is concerned with the concept of real-time technological adjustment of quality ratings to external impact and the development of the new combined method of carbon wire plastic deformation resulting in improving its mechanical properties is given as an example. The proposed concept is based on the principle of complex technological systems generation on the basis of precedent selection as well as on the application of vertical and horizontal adaptation. The authors show the results of complex theoretical and experimental investigation of various technological operations influence of the developed method on formation of the wire mechanical characteristics.
New technology for the production of high strength Invar alloys containing carbon, cobalt, and vanadium is considered. The formation of the alloys' mechanical properties is discussed. A basic system for the production of Invar blanks at metallurgical plants is described.
It is shown that new methods of severe plastic deformation design require combining different methods of plastic deformation. As for carbon steel wire, using drawing as a basic operation is obvious. The combination of drawing with bending and twisting was estimated by the stress-strain uniformity complex. It allows choosing the deformation processing conditions which ensure the uniform stress-strain state in each point of the carbon steel wire cross section. Based on such combination, a new method for manufacturing of semi-products with ultra fine grain structure by drawing with torsion was developed. The combination of wire drawing in two consecutively arranged dies with simultaneous bending and torsion allows achieving complex stress-strain state of the processed metal and ensure the share stresses. Metallographic investigation shows that such scheme of combined plastic deformation provides the uniformity of metal microstructure in its cross section.
