Two major classes of these compounds are substitutional and interstitial, the latter of which features a structure of alternating small and large molecules.
Removal of one of this kind of material's non-gold components is the subject of surface enrichment. This kind of material is necessary for diffusion to induce heating in the Kirkendall Effect. Precipitation heating can be used to strengthen these materials. A major class of these compounds governed by the double exchange mechanism features components that are not ferromagnetic, even though these as a whole are. Two major classes of these compounds are substitutional and interstitial, the latter of which features a structure of alternating small and large molecules. Examples of these materials include ferromagnetic ones named after Heusler, electrum, amalgam and bronze. For 10 points, identify these solid metallic solutions of two or more metals.
