Sonic-IR which is based on the thermographic detection of the temperature rise due to fric tional heating at the crack faces under ultrasonic excitation, has an advantage in the det ection of closed cracks. In this study, feasibility of the Sonic-IR technique for the dete ction of stress corrosion cracking is experimentally investigated by using plate specimens....

Sonic-IR which is based on the thermographic detection of the temperature rise due to frictional heating at the crack faces unde r ultrasonic excitation, has an advantage in the detection of closed cracks. Additionally, there is possibility to apply this te chnique to the inspection of complex geometry components because it is nearly non-contact technique. In this study, feasibility of the Sonic-IR technique for the detection of weld cracking is experimentally investigated by using small bore piping speci...

Abstract In a small diameter piping, stresses are generated due to internal fluid or pump vibrations especially around the welding parts. Authors have successfully de veloped a pipe strain sensor which is able to measure such stresses. Unlike conventional methods using strain gages and adhesive bond, the sensor can measure the stra in without putting adhesive bond on the piping surface. However, the strain sensor can provide measurements with a level of accuracy equivalent to that of conventiona l method u...

Two magnetic methods are proposed for the evaluation of initial degradations of type 304 stainless steel in stress corrosion cracking (SCC). The first one is the measurement of the distribution of chromium depletion by means of a magnetic force microscope (MEM). MEM observations are performed for some samples sensitized in various conditions, and the obtained results coincide with the expected ones from the chromium behavior. Moreover, the phase distributions in the solution-annealed and sensitized states a...
