摘要
Hot spinning process has attracted significant attention because it can be used to manufacture complex parts, extend the forming limit of materials, decrease forming forces and reduce process chains. In this paper, we review researches on lightweight metals spun at elevated temperatures since they are difficult to deform at room temperature. These metals include light alloys, such as titanium, magnesium and aluminum alloys, and metal composites. Then, the heating methods used in the hot spinning process and the treatment methods employed for the temperature boundary condition in finite element analyses for the process were discussed. Finally, the future development directions for the hot spinning process of lightweight but difficult-to-deform alloys were highlighted.
热旋成形因为可以用来制造复杂构件,提升材料的成形极限,降低成形力,减少加工工序而备受关注。本文综述室温下难变形的轻金属材料热旋成形的一些研究成果。这些金属包括钛合金,镁合金,铝合金等轻合金和金属复合材料。然后,讨论热旋成形中的加热方法以及对热旋成形有限元分析中温度边界条件的处理方法。最后,归纳总结难变形轻金属热旋成形的未来发展方向。
