Effect of Service Stress on Impact Resistance, X-ray Diffraction Patterns, and Microstructure of 25s Aluminum Alloy
This is a 1939 NASA technical report on 25S aluminum alloy, examining how service stress affects impact resistance, X-ray diffraction patterns, and microstructure. Its pictures are black-and-white micrographs and an X-ray diffraction pattern showing grain structure and slip lines, which a designer could use as texture references for metal, scratched surfaces, or scientific imagery with a radial starburst motif.
