Origin of the word " laves" in metallurgy

Origin of the word " laves" in metallurgy

(OP)
Why a phase called "laves" have this name ?

is it any link to volcanic science ?

Thanks man

but a when a explain to a friend the diffrents phases wich occurs in the solidification of an austenitix Stainless Steel.... he asked me why the word "laves" its' only for Magma and voclanic science, only that

Laves lava.
 
The Laves phase of unusual crystallographic structure is named for Fritz Laves (1906-1976), a noted crystallographer. His work extended our understanding of metallography of complex alloys & intermetallics.

"In 2006, there is an important jubilee not only for the Swiss crystallographic community. On February 27th, we celebrate the 100th birthday of Fritz Laves (27.2.1906-12.8.1978), who was from 1954 to 1976 professor for  crystallography and petrography at ETH Zurich. A detailed article on Laves' life and scientific contributions appeared in Zeitschrift für Kristallographie [vol.] 151 (1980) 1-20, and a special issue of the same journal dedicated to Laves will appear in May this year. In recognition of his pioneering work, the recent progress in understanding intermetallic phases will be reviewed. It is now fifty years ago, when Fritz Laves presented his ideas on the factors governing the structure of metals at a seminar on the Theory of Alloy Phases during the 37th National Metal Congress and Exposition, Philadelphia, 1955 (F. Laves: Crystal structure and atomic size. In Theory of Alloy Phases, pp. 124-198, Cleveland, ASM 1956). He came to the conclusion that „as a consequence of these principles (space-, symmetry- and connection principle) the stoichiometric formulae of intermetallic compounds are frequently fixed rather by the geometrical properties ... than by the formal valencies of the components“. By Laves's principles some peculiarities of structures could be explained that were not covered by „the three factors considered by Hume-Rothery (a) size factor, (b)electrochemical factor, (c) valence electron concentration“."

Thanks a lot kenvlach !

Actually it cames from :  Fritz LAVES !!!!

I am so confused,, i don't know this great man.

Thanks again Kenvlach !
