Abstract
The morphology and chemical analysis of the complex phases present in cast nickel aluminium bronze, of nominal composition 10% aluminium, 5% nickel and 5% iron, have been investigated using optical and electron microscopy techniques and energy dispersive analysis. It has been shown that α, β and four forms of κ can exist in the ascast microstructure of this alloy. Heat treatment can lead to the precipitation of a further κ phase which differs in morphology and chemical composition to those present in ascast structures.
