AI Technical Summary
Technical Problem
Existing technologies make it difficult to produce large-scale homogeneous magnesium alloy thick plates, and there are problems with poor plasticity and high production costs due to high rare earth elements.
Method used
Using magnesium alloy materials with low rare earth content, combined with array-type spiral forging and multi-directional forging processes, large-size thick magnesium alloy plates are prepared by refining grains and controlling the uniformity of microstructure through local deformation.
Benefits of technology
A thick magnesium alloy plate with uniform hardness was successfully prepared, solving the problems of poor plasticity and high production cost, and achieving improved uniformity and mechanical properties of large-format plates.

Abstract
本发明提供了一种大规格匀质镁合金厚板制备与成形方法，涉及镁合金加工技术领域。本发明是先制备低稀土含量镁合金铸锭，然后对镁合金铸锭进行多向锻造成形；再进行阵列式旋进锻造法成形；最后轧制成形。本发明制备的Mg‑5Zn‑1Gd‑1Y‑1Mn镁合金板材厚度为45mm，长轴1500mm，短轴长为1050mm，硬度在63～66HV，相比高稀土合金元素的添加，使用低含量稀土合金成分，节约了成本；利用阵列式旋进锻造法，极大地提高了材料的成形性与均匀性，操作简单、安全可靠。
