Abstract:

The report summarizes the results of a program to develop high-strength steels with improved reliability for use in aircraft structures. The most promising steels had very fine prior-austenite grain sizes about ASTM No. 15 produced by multiple-cycle rapid austenitizing. The results of studies to develop a conventionally heat-treated 10Ni-Cr-Mo-Co steel, studies of other types of ultra-fine-grained steels, and studies of the effects of purity on toughness and ductility are also reported.
