87 Mechanical Properties 871 Cast and Wrought Terminal Alloys

The mechanical properties of titanium alloys depend not only on the chemistry but are also strongly influenced by the microstructure as pointed out earlier, the latter in turn being dependent on the processing. The tensile properties of selected cast and wrought terminal titanium alloys are summarized in Table 8.2 [9].
