| 简介 |
A method for plasticity forming of wrought magnesium alloy containing rare earth elements comprises : subjecting the magnesium alloy, obtained by smelting, to heat treatment and peel off treatment; pre-heating it at 200-500℃ for a period from 20 minutes to 2 hours; and subjecting the pre-heated magnesium alloy to extruding, rolling or hot-rolling treatment. The ingredients of the wrought magnesium alloy are : 1.5-3.6wt% of Nd, 0.3-0.6wt% of Zr, 0-0.5wt% of Zn, 0-1.0wt% of heavy metal elements, 0-0.02wt% of impurities, and the balance of Mg. The prepared magnesium alloy has better plasticity and tensile/compression symmetry than traditional wrought magnesium alloy. |
