title: Reliability of reconstructed beta-orientation maps in titanium alloys.
abstract: This paper demonstrates that parent beta-orientation maps of titanium alloys can reliably be reconstructed from inherited alpha maps in most cases. Important aspects of the calculation that ensure an accurate determination of the parent orientation as well as a reliable restitution of the beta boundaries are discussed. The limits of the reconstruction method, according to the inherited alpha microstructure are also pointed out. Finally, the method is applied to a beta metastable titanium alloy, which contained enough retained beta phase so that its orientation could be measured by EBSD. The comparison between the measured and the reconstructed beta maps shows the efficiency of the method.
