On the Superplastic Deformation in Vanadium-Alloyed High-Nitrogen Steel
Metals, 2019 The experimental evidence for the realization of a superplastic behavior with 900% elongation in V-alloyed high-nitrogen austenitic Fe-19Cr-22Mn-1.5V-0.3C-0.6N steel was proposed. Using thermomechanical processing, a misoriented grain/subgrain austenitic

Nonclassical Austenite-Martensite Interfaces [PDF]
Le Journal de Physique IV, 1997 In the last 10 years a new theory of martensitic transformations based on nonlinear elasticity has been developed and intensively studied by J.M. Ball & R.D. James and others. Microstructures are understood in the theory as minimizing sequences for the total free energy, and are conveniently described using Young measures. For the case of the classical
