钛基五元合金、产品及制备方法技术

为了解决镍钛二元合金存在的弹性应力平台过宽、超弹性产生的温度区间较窄及合金晶粒过大问题，本发明专利技术提供了一种钛基五元合金。钛基五元合金包括Ｔｉ元素，还包括Ｎｉ元素、Ｃｕ元素、Ｃｒ元素、Ｂ元素，其中Ｎｉ元素占合金整体重量比为４５％－５５％，Ｃｕ元素占合金整体重量比为１％－１０％，Ｃｒ元素占合金整体重量比为０．１％－２％，Ｂ元素占合金整体重量比为０．１％－２％，其余为Ｔｉ元素和不可避免的杂质。本发明专利技术的钛基五元合金材料具有高弹性应变、优良的冷热加工性，适合制造口腔正畸治疗用矫形丝，制造的矫形丝柔和，易变曲。

Titanium based five element alloy, product and preparation method

The titanium alloy five element alloy is provided for solving the problem that the elastic stress platform of the nickel titanium two element alloy is too wide, the temperature interval produced by the superelasticity is too narrow and the alloy grain is too large. Five Yuan Ti alloy elements including Ti, including Ni elements, Cu elements, Cr elements, B elements, Ni elements for alloy overall weight ratio of 45% to 55%, accounting for Cu alloy elements overall weight ratio of 1% to 10%, accounting for Cr alloy elements overall weight ratio of 0.1% to 2%, the total B elements the weight ratio of 0.1%2% alloy, impurity elements and Ti for the rest of the inevitable. The titanium based five yuan alloy material of the invention has high elastic strain and excellent cold and hot processing property, and is suitable for manufacturing orthodontic orthopedic wires.
