Endurance and Other Properties at Low Temperatures of Some Alloys for Aircraft Use
This is a 1931 NASA technical report on how aircraft alloys behave at low temperatures, written for aeronautical engineers and researchers. Its pictures are plain technical charts, a wiring diagram, and black-and-white photographs of test apparatus and a fractured metal specimen, useful to a designer only as austere scientific graphics with grid lines, plotted data points, and utilitarian machinery.
