Research on Application of Shearography in SPF/DB Structure of Titanium Alloy |
| |
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... |
