Microstructural Characterisation of Cast Nickel Aluminium Bronze.

摘要

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 microscopy, scanning electron microscopy and scanning transmission electron microscopy, coupled to an energy dispersive analysis system. The development of the structure of nickel aluminium bronze from liquid metal to the room temperature structure has been followed and also the modifications to the structure produced by heat treatment.
