K. Ojima et al., DIRECT OBSERVATION OF ALPHA-]BETA TRANSFORMATION IN TIN BY TRANSMISSION ELECTRON-MICROSCOPY, Physica status solidi. a, Applied research, 139(1), 1993, pp. 139-144
Grey (alpha-phase)/white (beta-phase) tin interfaces are investigated
by transmission electron microscopy. Most of the phases separated by t
he moved alpha/beta interface have the three-dimensional orientation r
elationship of [011BAR]alpha \\ [001]beta, (111)alpha \\ (100)beta. Th
e observations on the alpha/beta interace indicate that the alpha -->
beta transformation in a thin foil of tin is mainly massive in nature
and is performed partially by martensitic transformation.
