Abstract
In this study, a dislocation-based model is presented for investigating the evolution of
microstructure and mechanical properties of thin lms during a wide range of straining. The model is
applied to the High Pressure Torsion (HPT) process of thin nickel disks that provides valuable information
on the evolution of material parameters during deformation. The model considers a free surface theory
for thin films and can explain the size effect phenomenon in agreement with previous reported trends in
literature.
