Corrosion Embrittlement of Duralumin V : Results of Weather-Exposure Tests
A 1929 NASA technical report on corrosion of Duralumin aluminium alloy after weather-exposure tests, issued as a numbered technical memorandum for engineers and researchers. The plate shows two photographs of outdoor exposure racks: a test specimen rack set among rocks at a Rock Bridge Canal air station, and a larger covered rack on wooden trestles at a Hampton-area testing site, with captions beneath each; a designer could draw on their plain, documentary look of weathered metal and industrial test equipment.
