Abstract : Explosion tear and drop-weight tear tests were conducted on specially processed quenched and tempered steels, on some maraging steels, and on some titanium alloys. The fracture toughness relationships are presented for these materials. The effects of precracking Charpy specimens of titanium on the shape of the Charpy curve and on crack initiation in the Charpy specimens are described. Preliminary crack growth rate studies on an HY-80 steel, a Ti-6A1-4V alloy, and a 2024 aluminum alloy, that were undergoing low-cycle fatigue, are described. Alloy development and welding studies on titanium are described and the mechanical properties of an NRL as-cast Ti-7A1-2Cb-1Ta plate are compared to those of a commercially produced plate of the same alloy.
