Abstract
A “gun” assembly for splat-quenching of materials in vacuum or controlled ambients has been set up. A metastable h c p structure (a=3.48 Å, c=5.59 Å, c/a=1.60) has been observed in splat quenched pure lead. The h c p phase is stable up to 270° C and transforms to the equilibrium f c c structure on heating in the electron microscope. The transformation has also been confirmed by DTA. The observed h c p structure appears to be stabilized by traces of oxygen as well as a high rate (∼ 108 K sec−1) of cooling. No such structure has been observed in vapour-quenched films under similar conditions.
