The influence of heat treatment on the microstructure and tensile
properties of the cast Ti-5111 alloy has been examined. The effects of
annealing temperature and cooling rate on the microstructural evolution in
this near-alpha alloy are assessed, and the relationships between
microstructure and the corresponding tensile properties and fracture
behavior are explored. The results indicate good strength in both the ascast
condition and after six different heat treatments. The study also
indicates heat treatments promoting a large prior beta grain size also
result in an occasional low value of tensile ductility in which failure occurs
due to crack initiation and growth.
