Abstract
The redistribution of Pt after heat treatment at 290 °C for 1 h has been analyzed by large-angle atom probe tomography assisted by femtosecond laser pulses. Two silicides Ni2Si and NiSi were found together with the solid solution of Ni and Pt. The redistribution of Pt at the Ni1âxPtx/Ni2Si interface is a clear illustration of the snowplow effect. A segregation of Pt at the Ni2Si/NiSi interface has been observed and is attributed to interfacial segregation.
