Abstract In order to improve the mechanical properties; magnetic field heat treatment was developed; which is a process combined temperature field and magnetic field together. By alternating magnetic field aging test; the effect of the magnetic field aging on mechanical properties of AA2219 aluminum alloy was studied by TEM analysis; Vickers hardness measurement; and mechanical tensile test. It is shown that alternating magnetic field can accelerate the aging precipitation process; and significantly improve the hardness and strength; The TEM images show that there is more precipitated phase and is bigger dispersion degree in the samples than those with the conventional. The microstructure and mechanical properties of the aluminum alloy were improved significantly by alternating magnetic field aging treatment. © 2015 Elsevier B.V;
