Product Introduction
Ti65 titanium alloy is a Ti-Al-Sn-Zr-Mo-Si-Nb-Ta-W-C alloy system near α high-temperature titanium alloy (hereinafter referred to as Ti65). It has moderate process plasticity and can be formed by traditional processes such as forging, rolling, and stamping. Adjust the ratio of primary equiaxial α to balance room temperature plasticity, high temperature persistence, and creep properties.
Product Specifications
1. Chemical composition
Ti-5.9Al-4.0Sn-3.5Zr-0.3Mo-0.4Si-0.3Nb-2.0Ta-1.0W-0.05C
2. Mechanical properties
Compared with traditional high-temperature titanium alloys, it is difficult to control the deformation resistance and microstructure uniformity of Ti65 alloys, so our company has carried out iterative optimization tests from conventional deformation to multi-deformation of mature high-temperature titanium alloy bars, studied the correlation law of microstructure properties between different fires of bars, and provided the necessary theoretical and application basis for subsequent optimization of hot processing technology and improvement of bar structure and performance.

Conclusion: Under the premise that the deformation in the β phase zone is sufficient, the tensile and persistent mechanical properties of Ti65 titanium alloy rods can be improved to a high level by forging 5 times, and the improvement of mechanical properties is not obvious due to continuous deformation, and the mechanical property gain effect caused by increasing the number of forging fires is significantly reduced.
