Preparation method of Mg-LRE (light rare earth element)-HRE (heavy rare earth element)-Zn deforming alloy with weak texture

The invention relates to the technical field of magnesium alloy materials, in particular to a preparation method of an Mg-LRE (light rare earth element)-HRE (heavy rare earth element)-Zn deforming alloy with a weak texture. The preparation method comprises the following steps of raw material preheating, alloy smelting, homogenizing treatment and plastic processing. A deforming magnesium alloy plate texture is weakened by a low-cost rare earth microalloying manner; an obtained deforming alloy plate has the weakened non-basal texture, so that the room temperature plastic forming ability of the magnesium alloy plate is improved; production equipment used by the method is common equipment; the method is simple in production technology and convenient to operate; the obtained alloy plate has a good forming property; and a microscopic structure is a uniform dynamic recrystallization equiaxed grain structure. 本发明涉及镁合金材料技术领域，具体涉及种具有弱织构的Mg−LRE−HRE−Zn系变形合金的制备方法；具体制备工艺如下：原料预热、合金熔炼、均匀化处理和塑性加工；具体是种通过低成本的稀土微合金化的方式来弱化变形镁合金板材
