Summary A technique is described for the quantitative microanalysis of a Cu‐Be alloy using parallel electron energy‐loss spectrometry. Spectrum acquisition and processing variables were optimized specifically for Cu—Be alloy spectra in an attempt to ensure that signal collection was equally efficient for both Be and Cu edges and that reliable, consistent results could be obtained from the subsequent quantification procedure. Analyses of the Cu Be γ–phase showed that the nominal composition of 50 at.% Be is not constant, and that Cu solubility increases slightly with increasing ageing temperature.
