TC6钛合金板材冷轧加工性能的研究

Research on property of cold-rolling TC6 titanium alloy plates

本文通过测试TC6不同冷轧加工率板材的性能,研究了TC6钛合金板材在冷轧过程中显微组织的变化规律和加工硬化曲线。研究结果表明:随着加工率的增加,TC6冷轧板材的宽展随之增大,显微组织逐渐拉长,极限加工率在30%左右;冷轧加工率控制在恰当的范围内,不仅有利于冷轧加工,而且通过热处理可以得到均匀的再结晶组织。

The microstructure evolution law and work hardening curve of TC6 titanium alloy plate during cold rolling is studied through testing different cold deformation plates in this paper. The result shows that with the increase of cold deformation,width spread of TC6 titanium alloy plate increases,and microstructures become elongated. The maximum deformation rate of TC6 plate is about 30%. Keeping cold rolling deformation in a proper range not only can benefit for cold rolling processing,but also can get uniform recrystallization grains.
