Abstract : In order to develop titanium alloys with higher ductilities and 0.1% yield strengths in the range of 190,000 to 240,000 psi and usable ductility in the range from 240,000 to 260,000 psi, 30 eight pound ingots were investigated and an additional 26 eight pound ingots are now being evaluated as part of Phase II. The data on 9 ingots from this second group is included in this report. Four alloys which showed promising properties in the 190,000-240,000 psi range as 8 lb. ingots were remelted as 80 lb. ingots for further evaluation as bar, plate and sheet material. Tensile tests at room temperature and -40 F impact tests have been completed on the bar stock and the plate for the four ingots. Welding experiments have been completed on the sheet and the data included herein. (Author)
