Fracture control guidelines for stress corrosion cracking of high strength alloys

Abstract

This document provides guidelines for obtaining and using stress corrosion cracking (SCC) test data for high strength alloys, which are used typically in aerospace structures. Both fracture mechanics and non-fracture mechanics tests are considered, but the emphasis is on using fracture mechanics as part of an overall strategy - a fracture control plan - to prevent or control SCC in service. In fact, the control of SCC in aerospace structures is not feasible, and SCC fracture control planning for high strength alloys in aerospace structures must be directed to preventing SCC in service.
