    Microstructural and Mechanical-Property Manipulation through Rapid Dendrite Growth and Undercooling in an Fe-based Multinary Alloy by Ruan, Ying, Dao, Ming, Mohajerani, Amirhossein

    Published 2017
    “…Once the dendritic growth velocity exceeds ~8 ms[superscript −1], the rate of Vickers microhardness increase slows down significantly with a further increase in dendritic growth velocity, owing to the microstructural transition of the (αFe) phase from a trunk-dendrite to an equiaxed-grain microstructure.…”

    Lithium Metal Penetration Induced by Electrodeposition through Solid Electrolytes: Example in Single-Crystal Li[subscript 6]La[subscript 3]ZrTaO[subscript 12] Garnet by Swamy, Tushar, Park, Richard J.-Y., Sheldon, Brian W., Rettenwander, Daniel, Porz, Lukas, Berendts, Stefan, Uecker, Reinhard, Carter, W Craig, Chiang, Yet-Ming

    Published 2021
    “…In single crystals, grain boundaries are excluded as paths for lithium metal propagation. Vickers microindentation was used to introduce surface flaws of known size. …”

    An in situ synchrotron X-ray study of reverse austenitic transformation in a metastable FeMnCo alloy by Wei, Shaolou, Kang, Jiyun, Tasan, Cemal C.

    Published 2022
    “…Although exponential attenuation is observed in both stacking fault probability and dislocation density upon the initiation of the transformation, the resulting microstructure (single-phase face-centered cubic structure) remains highly defected, exhibiting high Vickers hardness, but still preserving somewhat strain hardenability. …”

    Interfacial and Physical Confinement Effects on the Structure and Properties of Aligned Carbon Nanotube Architectures by Kaiser, Ashley L.

    Published 2022
    “…From PyC to 30 vol% A/C-NCs, 4 PIP cycles decreases porosity by ∼10 vol% and increases bulk density by ∼5% compared to 1 PIP; the 4 PIP A/C-NC bulk density decreases from ∼1.14 g/cm³ to ∼0.80 g/cm³ and porosity increases from ∼47 vol% to ∼74 vol%. Vickers microhardness testing in the axial CNT direction of A/C-NCs shows agreement with prior mechanical modeling and data at low vol% CNTs, where specific hardness increases from ∼3.3 GPa/(g/cm³) for PyC to ∼6.7 GPa/(g/cm³) for 30 vol% A/C-NCs, demonstrating that A/C-NCs are an advantaged superhard lightweight material. …”
