This report is a bibliography of the work reported in the literature on the effects of low temperature on the properties of structural materials. Some of the newer areas of cryogenic technology such as superconducting machinery involve environments which may subject the components to temperature as low as 4 K. Exposure of structural materials to such low temperatures affects their properties. This bibliography contains 963 references published between 1950-1976, arranged in chronological/alphabetical order. Combined material/property indexes are provided. (Author).

IN THE SOLUTION TREATED AND AGED CONDITION, Ti4Al-3Mo-1V has a higher ultimate strength than does Ti-2.5Al-16V, but the two alloys are about even in yield strength and elongation. In the solution-treated condition, Ti-4Al-3Mo-1V is unquestionably stronger than Ti-2.5Al-16V. These conclusions are independent of producer. There is not much difference in the same alloy produced by different companies. The alloys developed under the Titanium-Alloy Sheet-Rolling Program would not endure the most critical interpretation of release property specifications. On the other hand, these alloys come reasonably close to specifications. A complete set of release property specifications is available only for specimens that have been solution treated and aged. Such specimens do not all exhibit the desired ultimate and yield strength, but the percentage of rejects is small enough to be encouraging. (Author).
