摘要：

Here it was found that the homogenisation for rare earth magnesium alloy can be performed under pulsed current (422 degrees C/10 min), which is superior to the traditional industry one (520 degrees C/720 min). Because the pulsed homogenisation can promote atomic diffusion by conductivity difference between the Long Period Stacking Ordered (LPSO) phase and the alpha-Mg. The pulsed homogenisation can break the lamellar LPSO phase inside the grains and weaken element fluctuation.
