Abstract : Ratio Analysis Diagram (RAD) interpretive procedures have been evolved recently to provide generalized engineering solutions for fracture toughness assessments of structural titanium alloys. Failure-safe design also requires consideration of possible subcritical crack propagation (slow fracture) due to stress-corrosion cracking (SCC). Procedures for the incorporation of SCC characterizations into the RAD system have now been developed. These procedures serve the dual purpose of providing simplified interpretations of critical flaw size-stress instability conditions by the consideration of the resistance of the material to both fast fracture and SCC.
