![[Surface Relief due to Bainite]](https://www.phase-trans.msm.cam.ac.uk/images/relief1.gif)
High resolution measurements of the displacements caused by the formation of bainite in a steel have confirmed that the surface relief due to each platelet in any given sheaf is identical to that of the others in a sheaf, and that the relief of each subunit conforms with the general features of an invariant plane strain. The maximum observed shear strain was found to be about 0.26 which is consistent with the magnitude expected from the phenomenological theory of martensite crystallography. Clear evidence has also been obtained of the plastic deformation induced in the adjacent austenite by the growth of bainite.
