Abstract:

Tensile and bend tests were performed on the three base alloys, Ti-17V-10Cr-3A1, Ti-8Mo-8V7.5Fe-3A1 and Ti-15Mo-5Fe-3A1, containing additions of up to 5 Cu, Ni and Co. Complete replacement of Cr of Fe by Cu in the base alloys resulted in brittleness upon aging at 900F. Addition of up to 1 Si to Ti-17V-10Cr-3A1 increased tensile strength but lowered ductility after aging. Investigation of two metastable beta alloys was undertaken in the compositional range Ti-17V-1.5 to 4Fe-3A1 and Ti-8Mo-8V-1 to 3Fe-3A1 by hardness and tensile tests, and of two compositional ranges of stable non-hardening beta alloys, Ti-17V-10 to 12Mn-3A1 and Ti-8Mo8V-6 to 7Fe-3A1, by tensile, bend and impact tests. These indicated that Ti-17V-4Fe-3A1 and Ti-8Mo-8V-1Fe-3A1 were the better metastable beta alloys, and Ti-17V-11Mn-3A1 and Ti-8Mo-8V-6Fe3A1 the preferable stable alloys. Author
