Fabrication results, bend ductility, tensile properties at low and high temperature, high-temperature stressrupture data, welding studies, metallurgical studies (both recrystallization behavior and heat treatment), and oxidation behavior of tantalum and tantalum-base alloys, are presented. Several tantalum- base alloys were found to have outstanding strength properties at temperatures to 1925 deg C (3500 deg F), combined in many cases with excellent room-temperature ductility. Particularly outstanding in this respect are alloys in the system Ta-- Mo--W. (auth)
