Preferred Label : martensitic transition;
IUPAC definition : A diffusionless transition (first studied in the steel alloy, Martensite), at constant
composition, generated by coordinated atomic, ionic or molecular displacements over
distances smaller than interatomic distances in the parent phase. The cooperative
rearrangements of the crystal structure generally take place progressively by the
movement of a two-dimensional interface through the solid. Examples: The face-centred-cubic
to body-centred-tetragonal transition of iron containing some carbon; the transition
of tetragonal ZrO sub 2 /sub to monoclinic ZrO sub 2 /sub .;
