WELDABILITY STUDIES OF THREE COMMERCIAL COLUMBIUM-BASE ALLOYS

Abstract

A group of niobium-base alloys is being considered for addition to the Department of Defense Refractory Metals Sheet Rolling Program. Good weldability is one of the requirements. Two alloys under consideration are B- 66, and FS-85. A third alloy, C-129 was also included in this evaluation. Samples of these three alloys were obtained for a brief weldability evaluation to determine whether the alloys met the target properties established by the Materials Advisory Board, Refractory Metals Sheet Rolling Panel-Alloy Requirements and Selection Group. Bend tests made on base-metal samples showed that all alloys met the target properties for base metal. Bend tests of welds made in a vacuum-purged controlled-atmosphere chamber showed that only the welds in the FS-85 alloy possessed the desired target properties.
