Browse Topic: Non-destructive tests
Digital shearography has many advantages, such as full-field, non-contact, high sensitivity, and good robustness. It was widely used to measure the deformation and strain of materials, also to the application of nondestructive testing (NDT). However, most digital sherography applications can only work in one field of view per measurement, and some small defects may not be detected as a result. Multiple measurements of different fields of view are needed to solve this issue, which will increase the measurement time and cost. The difficulty in performing multiple measurements may also increase for cases where the loading is not repeatable. Therefore, a system capable of measuring dual fields of view at the same time is necessary. The carrier frequency spatial phase shift method may be a good candidate to reach this goal because it can simultaneously record phase information of multiple images, e.g. two speckle interferograms with different fields of view. It then obtains the phase
The purpose of this standard is to provide uniform methods for the ultrasonic inspection of wrought metals and wrought metal products.
The purpose of this standard is to provide uniform methods for the ultrasonic inspection of wrought metals and wrought metal products.
This specification covers procedures for ultrasonic immersion inspection of premium grade wrought titanium and titanium alloy round billet 5 inches (127 mm) and over in nominal diameter (see 8.5). Metal alloy billets other than titanium may be tested to this specification with the use of suitable reference standards.
