TLDR
In this paper, the authors present a general introduction to the theory of transformation kinetics of real metals, including the formation and evolution of martensitic transformations, as well as a theory of dislocations.

The divorced eutectoid transformation in steel

TL;DR: The divorced eutectoid transformation (DET) was shown to be faster in the presence of small spheroidal cementite particles with spacings on the order of a few microns as mentioned in this paper.

The Shape Memory (‘Marmem’) Effect in Alloys

C. M. Wayman, +1 more
TL;DR: In this paper, the shape memory effect can be universally correlated with a martensitic transformation that is thermo-elastic in nature, the thermoelasticity being attributed to ordering in the parent and martensite phases.
