| description | This study aims to understand the influence of heat treatment on behavior of AA6061 aluminum alloy at room temperature for various heat treatment. Two experimental parameters for this alloy are defined: micro hardness and the electrical resistivity, as a function of heat treatment at ambient temperature. The results show that the heat treatment conditions have an effective influence in mechanical properties of Al-Mg-Si aluminum alloy. This variation of the mechanical properties is the result of microstructural changes which have been observed using optical microscopy. When the material is subjected to a solution heat treatment followed by quenching and artificial aging, its mechanical properties, especially micro hardness and electrical resistivity, reach their highest levels and become very good compared to the other heat treatment applied to the same alloy.
Santrauka
Šio tyrimo tikslas – ištirti skirtingo terminio apdorojimo įtaką aliuminio lydinio AA 6061 savybėms. Siekta nustatyti, kaip terminio apdorojimo temperatūra veikia lydinio mikrostruktūrą ir elektrinę varžą. Tyrimų rezultatai rodo, kad terminis apdorojimas turi įtakos mechaninėms Al-Mg-Si lydinio savybėms. Šios įtakos rezultatas – tai mikrostruktūros pokyčiai, nustatyti optiniu mikroskopu. Terminiam apdorojimui pritaikant grūdinimo ir dirbtinio sendinimo režimus, pasiekiamas didžiausias mikro-kietumas ir elektrinė varža, palyginti su kitais terminio apdorojimo režimais.
Reikšminiai žodžiai: aliuminio lydinys 6061, terminis apdorojimas, mikrostruktūra, mikrokietumas, elektrinės savybės. |
