“…The microstructure of materials is closely related to their mechanical properties. MDF greatly improves its hardness and strength, which is mainly due to the fact that SPD occurs in the MDF process [24,25], which can significantly refine the grain structure. On the one hand, the number of grain boundaries increases with grain refinement; on the other hand, the density of dislocations within the material also increases dramatically due to the increasing amount of deformation, so the comprehensive effect of the grain refinement mechanism and dislocation theory enhances the degree of work hardening and leads to a substantial increase in the hardness of the material.…”

This study investigated the effects of multidirectional forging (MDF) and aging treatments on the wear properties of ZK61 magnesium alloy. Dry sliding wear tests were performed on homogenized, MDF, and aged samples using a friction wear machine to analyze the surface morphology by scanning electron microscopy (SEM) and white light interferometry, as well as the hardness and tensile mechanical properties. The ZK61 magnesium alloy has higher sliding wear properties after MDF due to higher strength, hardness, and work hardening. Grain refinement affects the wear resistance of the material, but aging increases the hardness and tensile strength and decreases the wear resistance.

“…However, pure titanium alloy without deformation or heat-treated have limited applications because of its low strength. To enhance its comprehensive mechanical performance, cold rolling method combined with heat treatment is applied to refine grain sizes of commercial pure titanium (CP-Ti) [14][15][16]. Sun et al [17] investigated the impacts of the rolling reductions on the textures and microstructures evolutions of CP-Ti sheets and developed an accurate crystal plasticity finite element model to predict its rolling deformation behaviors.…”

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.
