Abstract : Al-Cu alloys were characterized with an electron microbeam probe X-ray analyzer by examining the effects of alloying on AlK beta and CuL alpha X-ray emission spectra, and relating these effects to alloy composition. These effects include changes in spectra shapes, changes in intensity relationships, and band shifts. This method can be used to complement or substitute for the usual electron microbeam probe quantitative analysis. Speed and accuracy in measuring spectral changes are accomplished by using an automatic data acquisition and handling system that provides computer plotted spectra as well as a tabulated data printout. Two model Al-Cu systems were studied -- a diffusion couple and hypervelocity impact specimens. (Author)
