Abstract

Conversion Electron Mössbauer Spectroscopy (CEMS) studies are reported for as-cut and laser melted surfaces of Fe-Zr ingots in the 25-80 at.% Zr composition range. Disorder and amorphization was observed even on the as-cut surfaces due to the mechanical processing. Besides a significant enhancement of the non-crystalline fraction, surface melting by as laser pulses also results in the appearance of new metastable phases. Solidification via an extremely high cooling rate thus produces amorphous phase in composition ranges where its formation was previously assumed to be restricted to non melt-quenching methods only.
