Factors Affecting the Ductility and Microstructure of Ti-6a1-6v-2sn Titanium Alloy Weldments
The purpose of the investigation was to study the effect of material thickness, weld heat input and post weld heat treatment on the tensile properties and microstructure of Ti-6A1-6V-2Sn Titanium, and obtain a practical weld/thermal treatment cycle.The objectives were accomplished by electron beam and gas tungsten arc welding 0.060, 0.125 and 0.250 inch thick material and then heat treating at various temperatures and times. Electron beam and gas tungsten arc welding enabled an approximate 5:1 ratio of heat inputs to be utilized. Resultant welded and heat treated material was tensile tested and metallographically examined. Heat treatments involved both air and furnace cooling from temperatures as high as 1550°F.
