“…It is well known that the severe plastic deformation method is commonly applied to improve the mechanical properties of metallic alloys by grain refining [1,2]. Severe plastic deformation can be achieved when a material can overcome plastic deformation repeatedly without a shape change, that is, the original shape at the beginning of the plastic deformation is the same as that in the end [3].…”

“…This has gained increasing attention recently as a fast method that does not disrupt the materials structures and other properties [21]. Additionally, the indentation technique can probe a mechanical response to a very low applied load, and the behavior can be mechanically and physically analyzed [2]. The load-displacement curve obtained by microindentation experiment can not only obtain the relevant performance parameters of the elastic-plastic properties for the material quantitatively, but also reveal the microscopic deformation mechanism inside the material [22].…”

In this work, the effects of plastic deformation on the indentation behaviors of commercial pure titanium alloy were investigated. Titanium experienced various kinds of deformation by cold rolling processes, and the indentation behaviors were measured using microindentation. The results showed the most deformed sample experienced the largest indentation resistance and had the highest dislocation density and the indentation size influenced the indentation behavior of the CP-Ti. The effect of strain on Vickers hardness demonstrated the dominant role of the dislocation motion in the indentation deformation of CP-Ti alloy. The dependence of the indentation hardness on both the maximum indentation load and the indentation residual depth suggested there exists size effect in the indentation. The effect of the plastic strain on the energy ratio suggested the energy ratio is related to the microstructure in materials. Additionally, the linear relationship between the energy ratio on the indentation depth ratio was obtained for hcp-structured Titanium alloys.

Effects of plastic deformation on the indentation feature of hot-rolled commercial pure titanium alloy were detected using microindentation. It was found that the most deformed sample experienced the largest indentation resistance and had the maximum dislocation density and the indentation size influenced the CP-Ti indentation feature. The Vicker hardness and energy dissipated demonstrated the significant influence of the dislocation motion and size effects on the indentation in the indentation deformation. The linear relation of the energy ratio which is related to the microstructures and the indentation depth ratio was obtained for hcp materials Titanium alloys.
