Phased array ultrasonic inspection of stress corrosion cracking in austenitic cladding

摘要

Stress corrosion cracking (SCC) in austenitic stainless steel cladding is a topic of considerable concern to several major industries. TWI is presently involved in a range of R&D projects to improve the detection and characterisation of this damage mechanism in order to improve the structural integrity assessment of components post-fabrication and while in-service. Several methods of cladding exist in industry suited to different kinds of application.
