摘要
镍钛形状记忆合金管材在生物医学领域得到了越来越广泛地应用。塑性成形工艺是制造镍钛形状记忆合金管材的重要手段,镍钛形状记忆合金管材的塑性成形工艺方法包括正挤压、反挤压、可变形芯模挤压、无芯模拉拔、固定芯头拉拔、浮动芯头拉拔、可变形芯模拉拔和不可变形芯模拉拔。拉拔工艺仍是目前生产生物医用级镍钛形状记忆合金管材的主要手段。
The nickel-titanium shape memory alloy tube is more and more widely used in biomedical domain. The plastic forming processes play a significant role in manufacturing nickel-titanium shape memory alloy tube. The plastic forming processes of nickel-titanium shape memory alloy tube involve direct extrusion, indirect extrusion, deformable mandrel extrusion, hollow sinking, fixed plug drawing, floating plug drawing, deformable mandrel drawing and non-deformable mandrel drawing. The tube drawing process is still the main approach to manufacture biomedical nickel-titanium shape memory alloy tube at present.
