Abstract:Opravljena je numerična simulacija segrevanja in ohlajanja aluminijastih vzorcev med raztopnim žarjenjem in gašenjem. Simulacija je pripravljena z uporabo toplotne prehodnosti izračunane iz meritev temperature, kjer so vzorci obravnavani kot telesa idealne toplotne prevodnosti. Ugotovljeno je, da takšen pristop omogoča hitre in zadovoljive rezultate v primeru segrevanja dimenzijsko podobnih vzorcev med raztopnim žarjenjem. Pri ohlajanju med gašenjem z vodo ob predpostavki telesa idealne toplotne prevodnosti je napaka večja. Prikazane so meritve mehanskih lastnosti, ki pokažejo vpliv odstopanja izvedbe toplotne obdelave na končne lastnosti. Predstavljen je predlog oblikovanja velikostnih razredov vzorcev z namenom zmanjšanja razlik časov raztopnega žarjenja.

Title:Numerical Simulation of Heat Transfer During Heat Treatment of Aluminium Samples
Abstract:A numerical simulation of the heating and cooling of aluminium samples during solution heat treatment and quenching was carried out. The simulation is set up using the overall heat-transfer coefficient calculated by the lumped-capacitance method. This method was shown to produce quick and acceptable results in the case of heating dimensionally similar samples during a solution heat treatment; however, it produces greater error in the case of water quenching. Measurements of the mechanical properties are presented, which demonstrate the impact of the heat-treatment on the final properties. Sample-size classes are proposed to reduce the variation in the solution heat-treatment time.
Keywords:numerical simulation, heat transfer, lumped-capacitance method, aluminium, solution heat treatment, quenching, temperature measurement, mechanical properties
