Stress Corrosion Environmental Effects on AF 1410.

Abstract

AF 1410 plates available from Universal Cyclops through Air Force Materials Laboratory under contract F33615-73-C-5093 were welded using filler wire fabricated from sheet stock of the same composition as the base plate and from 1/16 inch Dia. weld wire prepared by Universal Cyclop from AF-1410 stock. The method of welding was cold wire-gas tungsten arc using manual feed. Satisfactory welds having mechanical properties as welded approaching the properties of the base plate in the double austenitized and aged condition were obtained. SCC tests demonstrated that nonhomogeneous microstructures in the fusion zone may result in nonuniform crack extension and seriously affect estimates made of KISCC.
