Theoretical bcc⇆fcc Transitions in Metals via Bifurcations under Uniaxial Load

Abstract

Pseudopotential models are used to study large strain, axial loading of the alkali metals. Various bcc $\rightleftarrows$fcc transitions are found to be associated with bifurcations from primary to secondary branch paths, under strict uniaxial load. Theoretically, other systems (e.g., the $\beta$-brasses) are expected to behave similarly.
