  This paper presents a review on the superplastic forming of Ti-6Al-4V alloy,
which has been used to manufacture parts of complex shapes and geometries. This
paper outlines the major work carried out on this front in the past three
decades. It covers various aspects related to experimental setups, including
the manufacture of dies and their modifications to maintain alloy thickness
uniformity after forming. A detailed study of the process parameters has also
been done to note the most important physical conditions required for
successful forming. This is followed by the influence of microstructure, modern
applications of superplastic forming of different titanium alloys and is
concluded with an insight into the future work and progress in this field.
