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. 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 -40F impact tests have been completed for three of the alloys at different heat treatments and the data is tabulated in this report. (Author)
