Abstract
A new method for extracting thermochemical values of surface and interface segregation in binary alloys from shifts in core-electron binding energies is applied to the case of Cu-Ni. The results for the heat of Cu surface segregation agree well with the calculated value. In addition to providing important thermochemical values this approach provides new insights into the relative importance of the different effects contributing to segregation phenomena.Keywords
