During usual synthesis (liquid solidification cooldown) the sequence of
phase formation can be gleaned from the phase diagram.
Beta = parent phase. It exists over a wide temperature range (from solidus to It has
six densest-packed (110) planes. Each contains two
dense-packed atom directions.
Upon phase transformation at or below the transus temperature (~1000C) the
newly forming alpha phase aligns a dense-packed [1 1 -2 0] direction along one
of the dense-packed [1 1 1]-parent directions. The Burgers’s orientation relation
between the product phase emanating from the parent beta phase is
