摘要
综述了高应变速率超塑材料及其变形机理和工业应用的最新进展。高应变速率超塑材料主要是铝基复合材料及铝合金 ,最近 ,对镁基复合材料、钛合金高应变速率超塑性能的研究也已开始。材料的高应变速率超塑性能使材料可进行超塑性锻造 。
The recent development of the high strain rate superplasticity(HSRS), its deformation mechanism and commercial applications are reviewed in the paper. This type of material includes Al alloy and Al based composite, and recently the HSRS of Mg_based composite and Ti alloy is investigated. The HSRS is very attractive for commercial application because it enables the material to be superplastic forged.
