abstract = {In the last decades, the class of Ti-rich TiAl-based
intermetallic materials has replaced many contemporary
alloys till 900 °C. Due to higher oxidation resistance,
$20\%$ lower density and higher (about 150 °C more)
operating temperature possibility of Al-rich TiAl alloys
over Ti-rich side, phases from the Al-rich region of this
alloy system are considered to be highly potential
candidates for high temperature structural applications.
Although there are a lot of works about Ti-rich alloys,
however, investigation from the Al-rich side is very
limited. This work reviews the class of Al-rich TiAl alloys
in terms of phases, microstructures, morphology, deformation
mechanisms, mechanical behaviors along with a possible
micromechanical modeling approach. Single crystal like
$Ti-61.8at.\%Al$ alloy from the Al-rich family has been
chosen as an example for modeling high temperature
anisotropy and tension-compression asymmetry. A possible
comparison with Ti-rich side is also presented.},
