Model predictions of volume contractions in transition-metal alloys and implications for laves phase formation-II

Journal Article · · Acta Metall.; (United States)
;

A simple cellular model estimate of the site volume changes attending alloying of transition metals with each other, and with alkali and alkaline earth metals is made. Application is made to AB/sub 2/ (MgCu/sub 2/ and MgZn/sub 2/) Laves phases as well as the related AB/sub 5/ (CaCu/sub 5/ and AuBe/sub 5/) structures. Size factors and electron factors are considered as measures controlling the occurrence of Laves phases.
