Attempt at Crystallization of a Nanocrystalline Structure in Thin Films of Fe73.5Cu1Nb3Si13.5B9 Alloy

An attempt is made to crystallize thin amorphous films of Fe73.5Cu1Nb3Si13.5B9 alloy in a nano‐crystalline structure. Thin films are prepared by the flash evaporation technique onto glass and rock‐salt substrates for electric resistance measurements and for structural studies, respectively. Observat...

Zusammenfassung:	An attempt is made to crystallize thin amorphous films of Fe73.5Cu1Nb3Si13.5B9 alloy in a nano‐crystalline structure. Thin films are prepared by the flash evaporation technique onto glass and rock‐salt substrates for electric resistance measurements and for structural studies, respectively. Observations of the changes in resistance on heating of the as‐deposited films allow us to investigate the changes in their structure. The electron diffraction and electron microscopic observations show the structural state of the samples as‐deposited and after annealing for 10 min at Ta1 = 633 K and Ta2 = 823 K. The results obtained indicate that the nanocrystalline structure can be formed in thin films of the studied alloy during annealing at Ta2, if the as‐deposited films were amorphous.
