TEM observation of recrystallisation in rapidly solidified hypercooled Co 80 Pd 20 alloy

Abstract

Applying the fluxing method, hypercooling was achieved in Co₈₀Pd₂₀ alloys. After recalescence, the rapidly solidified microstructures of hypercooled Co₈₀Pd₂₀ alloys were subjected to rapid quenching. Applying transmission electron microscopy, high densities of substructures, e.g. dislocations and subgrains, and migration of high angle grain boundaries suggest the occurrence of partial recrystallisation in the hypercooled Co₈₀Pd₂₀ alloys.
