Abstract
The phases present in an as-cast commercial nickel-aluminium bronze of nominal composition Cu-10Al-5Ni-5Fe have been characterized by optical and electronoptical techniques. Phase distributions andprecipitate morphologies have been studied by optical microscopy, scanning electron microscopy, and transmission electron microscopy. Analytical electron microscopy, both of thin foils and of extraction replicas, has been used to determine the composition of the various intermetallic K-phases.
