Corrosion and Fatigue of Aluminum Alloys: Chemistry, Micro-Mechanics and Reliability

Abstract

Lehigh University undertook a one-year multidisciplinary program of research, under AFOSR Grant No. F49620-96-1-0245 to continue to develop a basic mechanistic understanding of the material degradation processes of localized corrosion and corrosion fatigue crack nucleation and growth in aluminum alloys used in aircraft construction, and to formulate mechanistically based probability models for reliability assessments based on this understanding. This grant was an extension of the original 3-year program, under AFOSR Grant No. F49620-93-l-0426. This extension of research was initiated on 1 July 1996 and was extended to 31 December 1998. It is enhanced by a companion program sponsored by the Aging Airplanes Program of the Federal Aviation Administration (FAA) under Grant No. 92-G-0006. This final technical report summarizes research completed under Grant No. F49620-96-l-0245 over the period 1 July 1996 to 31 December 1998, and contains brief summaries of findings from Grant F49620-93-1-0426 and reflects contributions from the companion FAA sponsored program. Reprints and preprints of technical publications that resulted from these efforts are provided as a separate submission to the AFOSR Program Manager, and are available upon request to the Principal Investigator at Lehigh University.
