Numerical Simulation and Experimental Verification of Upsetting Temperature Optimization of Aluminium Alloy

Maros Martinkovic, Maria Kapustova

Abstract


Warm forming of metal materials represents a profitable method of precise forming pieces production due to energy and time savings, obtaining of higher surface quality and dimension precision of forming pieces in comparison with hot forming. An optimal forming temperature was selected from experimental measurement of mechanical properties, plasticity and workability of an aluminium alloy. Upsetting forming process of aluminium alloy AlSiMg type was simulated using finite element method at warm forming temperatures. Numerical simulation of the alloy forming based on finite elements methods was verified, the results of the numerical simulation were compared with experimental result - degree of grain boundaries deformation obtained by stereological metallography. From the results an optimal temperature of warm forming was estimated.
