The Effect of Continuous Weathering on Light Metal Alloys Used in Aircraft
This 1939 technical report from the NASA Technical Reports Server, a NACA-era study, examines how continuous weathering corrodes light metal alloys used in aircraft, written for aeronautical engineers and materials researchers. Its pictures are plain black-and-white photomicrographs and close-up panels of labelled alloy specimens, showing corrosion attack from pitting and surface roughening to deep dark etching; a designer might take from them only a sense of documentary scientific imagery, with its grid of labelled rectangles and high-contrast surface textures.
