Brian Cantor led a team that developed one of these materials consisting of an equal mixture of five first row transition metals. For 10 points each:
[10e] Name these materials said to be “high-entropy” or “multi-component” when they contain at least five different metals. More common two-component examples of these materials include bronze.
ANSWER: alloys [accept high-entropy alloys or multi-component alloys]
[10h] The Cantor alloy undergoes a phase separation into metallic and intermetallic phases, an example of a decomposition described by this term. The zero set of the second derivative of Gibbs free energy with respect to composition percentage defines a curve described by this term.
ANSWER: spinodal [accept spinodal decomposition or spinodal curve]
[10m] The “sluggish diffusion” effect in high-entropy alloys results from unequal lattice potential energies around the “vacancy” type of these sites. Other types of these sites may be classified as “substitutional” or “interstitial.”
ANSWER: point defects [or crystallographic point defects; accept vacancy defects or substitutional defects or interstitial defects]
