摘要
超细晶材料具有优异的超塑性能,综述了通过大塑性变形方法获得镁、铝合金超细晶材料的超塑性能研究进展和通过大塑性变形和热氢处理获得超细晶钛合金的超塑性能,展望了超细晶轻合金的发展趋势。
Ultrafine-grained materials have excellent superplastic properties.In this paper,the superplastic properties of ultrafine-grained magnesium and aluminum alloys obtained by severe plastic deformation were summarized.The superplastic properties of ultrafine-grained titanium alloys prepared through severe plastic deformation and thermohydrogen treatment were reviewed.Finally,the development trend of ultrafine-grained light alloys was prospected.
