Laves phasen.

Brit.

/ˈlɑːvəs feɪz/, U.S.

/ˈlɑvəs ˌfeɪz/

Etymology: < German Laves-Phase (G. E. R. Schulze 1939, in Zeitschr. f. Elektrochem. XLV. 850/1) < the name of Fritz-Henning Laves (1906–78), German crystallographer + Phase phase n.²

Metallurgy.

Any of a group of intermetallic compounds of composition approximately AB₂ in which the relative sizes of the A and B atoms are such as to allow a stable packing arrangement with unusually high co-ordination numbers.

Laves phase1940

1940 Chem. Abstr. 34 1895 Laves phases are AB₂ intermetallic compds. whose structure and combination mechanism are detd. by the crystal lattice.

1956 W. Hume-Rothery & G. V. Raynor Struct. Metals & Alloys (ed. 3) v. 228 The Laves phases crystallize in one of three closely related structures, and are isomorphous with the compounds MgCu₂, MgZn₂, or MgNi₂.

1967 A. H. Cottrell Introd. Metall. xiv. 195 In a Laves phase AB₂, each A atom has 16 neighbours (4A and 12B) and each B atom has 12 neighbours.
