Abstract

In this work the study of the dependence of the critical temperatureMs for the onset of martensite in noble metal (NM)-based ternary alloys in extended to some new cases of interest, for which experimental data are now available.A recently developed model connecting surface segregation and martensite nucleation is applied, which on the one hand gives information in agreement with experimental data, and on the other allows for a critical comparison between the obtained results and the theoretical predictions in the framework of related predictive theories for surface segregation.
