Paper Title:
HRTEM Analysis of Aging Electrolytic Low-Ti Al Alloy
  Abstract

Electronic tensile testing, scanning electron microscope, transmission electron microscope, X-ray diffractometer and high resolution transmission microscope were employed to investigate the mechanical properties, microstructure, tensile fracture and morphology of the precipitated phases of an electrolytic low-titanium wrought 6009 aluminum alloy. Results showed that the mechanical properties of the electrolytic aluminum sheet were improved by solid solution treatment incorporating with pre-aging treatment. The tensile strength and extensibility were enhanced by a factor of 23% and 38% by pre-aging treatment at 150 °C for 5 minutes respectively; a large quantity of nucleation sites of β˝ phase were generated by pre-aging treatment, which was propitious to the transformation from solid solution state to GP zone, and the stable size of GP zone formed during the pre-aging process promoted the precipitation of Mg2Si phase. The Mg2Si phase was revealed by HRTEM and the crystalline stripes were obtained by Fourier transformation.
