Detection of macrosegregation in a large metallic specimen using XRF

E. J. Pickering and M. Holland

Abstract

The characterisation of macroscopic chemical segregation in engineering components over length scales of many metres can be an arduous task. This report investigates the implementation of a technique that is capable of mapping long range variations in the chemical composition of metal components, without the need for extensive sample preparation. The capability of the method is optimised for large production components in a setting where process parameters such as measurement time and minimal surface preparation are of importance. Hence, a readily available hand held X-ray fluorescence instrument and analysis software are used to map macrosegregation in a low alloy steel slab.
