Research on Application of Shearography in SPF/DB Structure of Titanium Alloy
分析了钛合金 SPF/DB 结构缺陷及形成原因,介绍了错位散斑技术的基本原理,通过采用错位散斑技术对钛合金 SPF/DB 结构进行检测试验,能够发现明显的缺陷特征,从检测敏感度、效率等方面与 X 射线、超声 C 进行对比,结果表明,错位散斑技术能够应用于钛合金 SPF/DB 的结构检测,但仍需在检测精度、可靠性等方面进行深入研究。
Abstract
The defect and reason in superplastic forming and diffusion bonding on titanium alloy are analyed. The basic principle of shearography is introduced. By using the shearography on SPF/DB of titanium alloy
some obvious characteristics of the defect are obtained. Shearography technique is compared with X-ray and ultrasonic on sensitivity
reliability
and so on. Shearography is proved to be an effective technique on SPF/DB of titanium alloy
but the precision and reliability of the technique should be studied deeply in the future.
