Dr Alan Turnbull FREng FRS
NPL Senior Fellow, Materials Division, National Physical Laboratory
Alan Turnbull is distinguished for his mathematical modelling of corrosion processes, particularly the complex interaction between mass transport and chemical and electrochemical reactions in the restricted geometries of cracks, crevices and pits. Supported by innovative in-situ measurement, this provides the scientific foundation for rationalisation and prediction of the effect of environmental variables on environment assisted fracture and for control of localised corrosion in a very wide range of industrial applications including oil and gas, marine, chemical and nuclear engineering. He has extended his work to integrated models for hydrogen generation, diffusion, and trapping in metals, and to the prediction of the evolution of cracks from corrosion pits.
