Some solid-state phase transformations in steels occur without diffusion. The change in crystal structure is instead achieved by a homogeneous deformation of the parent crystal into that of the product. It follows that the shape of the crystal changes during the course of transformation.

This shape deformation can in principle be exploited to cancel the residual stresses that develop when welds are made in constrained assemblies. But the process requires control of the specific crystals that form, and of the phase transformation temperatures. The underlying science will be explained together with specific examples of commercial applications.
