Abstract:
Asymmetric cryorolling is a technique that combines the features of asymmetric rolling and cryorolling, and can be used to produce ultrafine grained aluminum sheets. The problem with asymmetric cryorolling is the heat generated in the roll gap by high contact friction and the plastic deformation. [..]

Abstract:
In this study, we will examine the phenomenon of precipitation that appears in the aluminum alloy AGS wires. Since the studied wires are drawn, we will try to see also the effect of the deformation on this phenomenon.The precipitation was believed to be the main cause of hardening in the AGS 6101 wire rod.

Abstract:
The expanding range of applications for parts made of light metals (magnesium, aluminium or titanium) could lead to a replacement of parts made of steel by the ones manufactured from light metal parts. However, magnesium and aluminium parts in particular reach their technical limits when exposed to high tribological, mechanical or thermal stress. [..]

Abstract:
This article is focused on analysis of state formation which influences the tubes production process from austenitic stainless steels with diameter 0.34 mm in a negative way. The problems have been concentrated on factors monitoring which affect the drawing process stability of seem tubes where the desired final dimensions – a diameter 0.34 mm and a wall thickness 0.057 mm have been limited factors.

Abstract:
The zinc coating both increases the corrosion resistance and lubricated to minimize the friction for subsequent diameter reduction steps. The course of the reaction between the steel surface and the molten zinc depends upon the formation and growth of the iron-zinc alloy layers. [..]

Abstract:
Intensity of structural changes during forging is usually determined in dependence on the forging ratio. Forging ratio at elongation is most often calculated with use of simple relations, which are based on the change of cross-section of the forged pieces. [..]
