Determination of the coefficients of rheological equation of Al–Zr alloy under hot plastic deformation conditions
Aluminum alloy wire rod is the basic material for manufacturing wires for overhead power lines constructed in the areas with different atmospheric conditions. There is a potential associated with the use of wire rods made of aluminum-zirconium alloys, which can improve the performance characteristics of the final products. This study is devoted to a method for determining rheological coefficients of the equation linking the strength properties (σs) of alloy Al–0.15Zr with deformation parameters (\(\overline{\upvarepsilon }\) and ξ) at process temperatures ranging from 300 to 500 °C. The coefficients were calculated based on the experimental data obtained during indirect determination of the deformation resistance by measuring the force of direct hot extrusion. The variable parameters of the experiment included: elongation ratio (λ), deformation temperature (T), and extrusion velocity (υex). For each equation coefficient, characteristic curves demonstrating their dependence on the process temperature were plotted and used to find an approximating function.
