Abstract: Characteristic densification in cold sintered microstructures could also have a strong influence in defining their mechanical response. For the first time, nanoindentation and micro-pillar testing is used to study these details. Based on our recent work, we selected cold sintered (250 °C, ∼ 99 % dense) and conventionally sintered (900 °C, ∼ 98 % dense) ZnO samples. Hardness, elastic modulus and compressive stress of cold sintered samples were measured to be 5.5 GPa ± 0.5, 100 GPa ± 5 and ∼ 1.2 GPa, respectively. Same values for conventionally sintered ZnO were 4.8 GPa ± 0.6, 109 GPa ± 6 and 0.8 GPa, respectively. The distinctive nature of grain boundary regions in cold sintered samples were found to influence the deformation behavior of these samples, as confirmed by TEM investigations. Our study reveals the potential of cold sintering and use of selected testing techniques as suitable choice.
