Closed die forgings for automotive applicationsKevorkijan, VaružanIn this study, redesigning for equal functional properties and rapid prototyping of hot forged automotive parts based on commerically available wrought magnesium alloys (AZ80) and composites ... (AZ80/SiC/12p) were performed. To achieve the same functional properties in a forged automotive component irrespective of the structural material selected, an automotive connecting rod, currently mass-produced in aluminium alloy 6061, was redesigned for usage of wrought magnesium alloy (AZ80A) and particle reinforced magnesium alloy matrix composite (ZC71/SiC/12p). By applying conventional hot forging technology, prototype connecting rods were forged, trimmed and heat treated on a semi-industrial scale. The microstructure of both as-extruded and hot forged species was examined and the tensile properties of AZ80, ZC71/SiC/12p, 6061 and 6061/SiC/15p testing bars machined from hot forged connecting rods were measured. Weight reduction in the redesigned connecting rods was determined and the submission of magnesium and aluminium-based materials for steel was compared in terms of cost in order to demonstrate the main economic advantages.Vir: Aluminium. - ISSN 0002-6689 (Vol. 79, 7/8, Jul.-Aug. 2003, str. 608-612)Vrsta gradiva - članek, sestavni delLeto - 2003Jezik - angleškiCOBISS.SI-ID - 8117782
