摘要：

Ni-15 Cr-24 Al-0. 3 Zr (at. %) was studied. Surface segregation of zirconium is reported for the first time. The surface of the unheated alloy showed no zirconium using a Scanning Auger microscope, despite the presence of zirconium-rich precipitates which were observed on the surface using EPMA electron probe microanalysis.
