    Yandong Wang is currently a Changjiang distinguished professor in the State Key Laboratory for Advanced Metals and Materials, University of Science and Technology Beijing. His research topics include: (1) applications of the neutron and synchrotron x-ray diffraction methods to the studies of deformation and phase transformation; (2) research development of ferromagnetic shape-memory materials or metallic alloys with superelastic behavior; and (3) simulations of mechanical properties by various microscopic models. He received the NSFC Outstanding Young Scientist Award in 2007. His research team was awarded as one of the excellent Sci-Tech innovation teams by Ministry of Science and Technology of China in 2019. He has over 350 publications in referred journals, including Science, Nature, Nature Materials, PNAS et al.

Introduction

The confined martensitic transformation (CMT) exhibits its specific transformation crystallography, thermodynamics and kinetics, which are obviously different from that observed in traditional martensitic transformation (TMT). CMT can be classified into two kinds of categories, i.e the weak first-order phase transformation and the continuous phase transition, which has been evidenced in a broad alloy spectrum such as shape memory alloys and complex concentrated alloys. Main significant progresses on CMT will be presented with a focus on fundamental research areas involving the concept, transforming characterization, and unprecedented mechanical properties. The underlying physical origin on the CMT mechanisms and in-depth understanding of CMT-associated properties will be shown, which was mainly achieved by synchrotron-based X-ray and neutron diffraction experiments.
