Abstract

Abstract : Effects of non‐isothermal aging treatment on mechanical properties and corrosion resistance of Al–Mg–Si aluminum alloy were investigated by hardness test, tensile test, intergranular corrosion test, and TEM observation. The results suggested that the NIA process (heating from 30 °C to 190 °C at 20 °C/h) is capable of enduing higher mechanical performances and comparable corrosion resistance to Al–Mg–Si alloys, as compared with that of the T73 condition. The different evolution of precipitates in intra‐grain and grain boundary is supposed to explain the various mechanical performances and corrosion resistance. Abstract : The effects of different aging treatments (T6, T73, and non‐isothermal aging process) on the precipitation behavior, mechanical properties, and corrosion resistance of Al–Mg–Si alloys are investigated. The non‐isothermal aging process (heating from 30 °C to 190 °C at 20 °C/h) is capable of enduing higher mechanical performance and comparable corrosion resistance to Al–Mg–Si alloys, as compared with that of the T73 condition.
