Contribution of early works by Terence G. Langdon to modern materials science

Professor Terence G. Langdon has been ranked as the second most cited author in materials science of the last 10 years by the international Institute for Scientific Information (Philadelphia, PA, USA). An analysis of his works shows that his most highly cited publications are those dealing with recent studies of microstructural evolution and mechanical properties of ultrafine-grained (UFG) materials processed by severe plastic deformation, as well as earlier papers on creep and superplasticity carried out in the 1970–1980s. This paper overviews the landmarks in the research activity of Prof. Langdon, and traces how his early works have affected the current investigations of the mechanical behavior of UFG materials produced by severe plastic deformation.
