Spinodal decomposition: Difference between revisions

Spinodal phase decomposition has been used to generate architected materials by interpreting one phase as solid, and the other phase as void. These spinodal architected materials present interesting mechanical properties, such as high energy absorption,<ref name="Bauer et. al.">{{cite journal |last1=Guell Izard |first1=Anna |last2=Bauer |first2=Jens |last3=Crook |first3=Cameron |last4=Turlo |first4=Vladyslav |last5=Valdevit |first5=Lorenzo |title=Ultrahigh Energy Absorption Multifunctional Spinodal Nanoarchitectures |journal=Small |date=November 2019 |volume=15 |issue=45 |pages=1903834 |doi=10.1002/smll.201903834|pmid=31531942 |s2cid=202672680 }}</ref> insensitivity to imperfections,<ref name="Hsieh et. al.">{{cite journal |last1=Hsieh |first1=Meng-Ting |last2=Endo |first2=Bianca |last3=Zhang |first3=Yunfei |last4=Bauer |first4=Jens |last5=Valdevit |first5=Lorenzo |title=The mechanical response of cellular materials with spinodal topologies |journal=Journal of the Mechanics and Physics of Solids |date=1 April 2019 |volume=125 |pages=401–419 |doi=10.1016/j.jmps.2019.01.002|arxiv=1904.06733 |bibcode=2019JMPSo.125..401H |s2cid=118645530 }}</ref> and high stiffness-to-weight ratio.<ref name="Li et. al.">{{cite journal |last1=Zheng |first1=Li |last2=Kumar |first2=Siddhant |last3=Kochmann |first3=Dennis M. |title=Data-driven topology optimization of spinodoid metamaterials with seamlessly tunable anisotropy |journal=Computer Methods in Applied Mechanics and Engineering |date=September 2021 |volume=383 |pages=113894 |doi=10.1016/j.cma.2021.113894|arxiv=2012.15744 |bibcode=2021CMAME.383k3894Z |s2cid=229923529 }}</ref> Furthermore, by controlling the phase separation, i.e. controlling the proportion of materials, and/or imposing preferential directions in the decompositions, one can control the density, and preferential directions effectively tuning the strength, weight, and [[anisotropy]] of the resulting architected material.<ref name="Kumar et al">{{cite journal |last1=Kumar |first1=Siddhant |last2=Tan |first2=Stephanie |last3=Zheng |first3=Li |last4=Kochmann |first4=Dennis M. |title=Inverse-designed spinodoid metamaterials |journal=npjNPJ Computational Materials |date=December 2020 |volume=6 |issue=1 |pages=73 |doi=10.1038/s41524-020-0341-6|bibcode=2020npjCM...6...73K |s2cid=219315003 }}</ref> Another interesting property of spinodal materials is the capability to seamlessly transition between different classes, orientations, and densities,<ref name="Kumar et al"/> thereby enabling the manufacturing of effectively multi-material structures.<ref name="Senhora et. al.">{{cite journal |last1=Senhora |first1=Fernando V. |last2=Sanders |first2=Emily D. |last3=Paulino |first3=Glaucio H. |title=Optimally‐Tailored Spinodal Architected Materials for Multiscale Design and Manufacturing |journal=Advanced Materials |date=27 April 2022 |volume=34 |issue=26 |pages=2109304 |doi=10.1002/adma.202109304 | pmid=35297113 |s2cid=247498613 }}</ref>
