V članku je predstavljena raziskava optimizacije toplotne obdelave aluminijeve zlitine AlSi10MgMn, ki se uporablja pri izdelavi komponent za električna vozila. Namen raziskave je bil doseči optimalno kombinacijo trdnosti, trdote in raztezka z nadzorom parametrov raztopnega žarjenja, gašenja in staranja. Eksperimentalno delo je vključevalo termodinamične izračune s programom Thermo-Calc, analize diferenčne vrstične kalorimetrije (DSC), mikroskopske preiskave ter meritve trdote in natezne trdnosti. Rezultati so pokazali, da zvišanje temperature raztopnega žarjenja na 500 °C ter staranje pri 210 °C omogočata dosego najvišjih vrednosti trdote in zadovoljive kombinacije mehanskih lastnosti. Optimalni pogoji so bili določeni pri raztopnem žarjenju na 465 °C 2 h, ohlajanju v vodi in umetnem staranju na 230 °C 2 h. Takšni pogoji so zagotovili natezno trdnost 201 MPa, napetost tečenja 147 MPa in raztezek 4,5 %.

Abstract

The article presents a study on optimising the heat treatment process of the aluminium alloy AlSi10MgMn, which is used in the production of components for electric vehicles. The aim of the research was to achieve an optimal combination of strength, hardness, and elongation by controlling the parameters of solution annealing, quenching, and ageing. The experimental work included thermodynamic calculations using Thermo-Calc software, differential scanning calorimetry (DSC) analyses, microscopic examinations, and measurements of hardness and tensile strength. The results showed that increasing the solution annealing temperature to 500 °C and ageing at 210 °C produced the highest hardness values and a satisfactory combination of mechanical properties. The optimal conditions were determined to be solution annealing at 465 °C for 2 h, water quenching, and artificial ageing at 230 °C for 2 h. Under these conditions, a tensile strength of 201 MPa, yield strength of 147 MPa, and elongation of 4.5% were achieved.
