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.},
