Abstract

Site occupancy has been determined using the channelling-enhanced microanalysis for a Ni3(Al, Ta) intermetallic compound with the L12-type crystal structure. It is shown that there is a large scattering of data points for [001] beam incidence compared with [111] beam incidence. The reasons for this difference are examined by simulating channelling electron distribution on the A1 and Ni columns. It is concluded that the large scattering for the [001] beam incidence is due to the indistinguishable difference between channelling electron intensities on the A1 and Ni columns.
