Particle desorption from the surface of an amorphous metallic alloy

The desorbed particle flux accompanying crystallization and melting in amorphous alloys was studied by means of temperature programmed desorption (TPD). Ribbons of the two amorphous alloys, Fe sub 77 Ni sub 1.2 Si sub 8.5 B sub 13 and Fe sub 38 Ni sub 36 Cr sub 8 B sub 18 were used for the desorptio...

Description
Summary:	The desorbed particle flux accompanying crystallization and melting in amorphous alloys was studied by means of temperature programmed desorption (TPD). Ribbons of the two amorphous alloys, Fe sub 77 Ni sub 1.2 Si sub 8.5 B sub 13 and Fe sub 38 Ni sub 36 Cr sub 8 B sub 18 were used for the desorption study. Desorption fluxes over the temperature range from 300 to 1400K were measured for potassium and copper atoms (impurities), iron, nickel, boron atoms (alloy components), BO, and B sub 2 O sub 3 molecules. The results showed that the structural transition of amorphous to crystalline is accompanied by intensive surface segregation and desorption of both alloy components and impurities.
