摘要
Ti26合金(Ti-15V-3Al-3Cr-3Sn-1Nb-1Zr)是一种高强近β钛合金,具有优良的冷成型性、高的强度、抗疲劳性能及较好的焊接性能,使得该合金还可以制作板材、管材等半成品。采用钻孔挤压和斜轧穿孔工艺制备出了高强Ti-26合金管坯,对热加工后的管坯组织性能及热处理工艺进行了研究。结果表明:采用两种工艺均可制备出高强钛合金管坯,而斜轧穿孔工艺简单,材料利用率高。对加工后的管坯进行了固溶处理,均可以获得后续冷加工所需组织性能。
Ti26 alloy （Ti-15V-3Al-3Cr-3Sn-1Nb-1Zr） is a high-strength beta titanium alloy with excellent cold molding, high strength, fatigue properties and good welding properties. It is also used in sheet and pipe. The Ti26 alloy tube was successfully obtained by extruding and rotary piercing process; Its microstructure, properties and heat trcatment process of the tube were studied. The results show that the high-strength tubes can be manufactured by the two methods, while rotary piercing process is simple and high material utilization. The high-strength tubes after solution treatment can obtain microstructure and properties for matching subsequent cold working.
