Abstract:
Simple laboratory-type tests to evaluate the toughness of high strength sheet alloys and their complex welded joints at cryogenic temperatures were developed. The mechanical properties of materials currently being used or proposed for use in cryogenic-fueled missiles and space vehicles were also investigated. Tests employed for evaluating the toughness of sheet materials included notched tensile tests having stress concentration factors of 3.2, 6.3, and 19, crosstension and tensile shear tests of individual resistance spot welds, and tensile tests of simple fusion welds. These tests were conducted at 78, -100, -320, and -423 F. These data, as well as data obtained from tensile tests of the base metal, percent martensite determinations, and metallographic examinations of fractured coupons, were correlated with low-cycle, highstress fatigue data obtained on complex welded joints at 78, -320, and -423 F.
