In-situ deformation experiments are reviewed on the subjects of martensitic transformation and shear deformation. Particular interest is directed to our recent studies dealing with γ→α and γ→ε martensitic transformations, dislocation reactions in proton irradiated Mo and steels, and dislocation motion in a high temperature strengthening alloy of ordered Ni3Al.
