摘要：热辅助板料渐进成形技术属于传统板料渐进成形技术的种拓展，特别适用于加工室温条件下难成形的材料。其中，基于摩擦致热原理和电加热原理的热辅助板料渐进成形技术在工艺柔性、装备成本、系统集成复杂度等方面更具优势。主要研究了两种热辅助板料渐进成形技术在加工过程（加工效率和加热效率)中的不同特点；同时，着重探讨了两种技术对不同材料的适用性。研究表明，摩擦致热和电加热板料渐进成形技术在加工效率和加热效率方面各具优势；综合考虑，摩擦致热渐进成形技术更适用于镁合金AZ31B的加工，而电加热辅助板料渐进成形技术更适用于钛合金 Ti6A14V的加工。

A study of applicability for two heat-assisted incremental sheet forming technologies
XUDong-kai，CHENJun
Abstract: Heat-assisted incremental sheet forming (H-ISF) which as a variant of conven-tional ISF is cspecially suitable to process hard-to-form materials in room temperature condi-tion. Frictional stir-ISF and elcctric assisted-ISF are superior to other H-ISF technologies in terms of process flexibility,equipment cost,system complexity and etc.In this study,the proccss characteristics of these two technologies including processing efficiency and heating rate are investigated in dctail. Also, proccss capabilities are compared by forming different materials. The investigation results show that frictional stir-ISF and electric assisted-ISF have their own advantages in processing efficiency and heating rate, respectively. It indi-cates that frictional stir-ISF is suitable to fabricate magnesium alloy AZ31B, while electric assisted-ISFis suitable for titanium alloyTi6Al4V.
Keywords: incremental sheet forming; hard-to-form materials; frictional hcating; electric heating
