Sensitization in 5XXX aluminum alloys is an insidious problem characterized by the formation of beta phase (Al3Mg2) at grain boundaries, which increases the susceptibility of alloys to intergranular corrosion (IGC) and intergranular stress-corrosion cracking (IGSCC). The currently accepted method for quantifying Degree of Sensitization (DoS) of AA5XXX alloys is the ASTM G67 Nitric Acid Mass Loss Test. However, it is a destructive and time-consuming method. A fast, reliable, and nondestructive method for rapid detection of DoS in AA5XXX alloys in the field is highly desirable. In this proposal, Intelligent Automation, Inc. (IAI) and Prof. Robert B. Pond, Jr. from Loyola College propose an innovative non-contact ultrasonic technique for fast quantification of DoS in Al-Mg alloys.
