Abstract

The effect of cryogenic cycling treatment on the elastic properties of a Fe48Cr15Mo14C15B6Y2 bulk metallic glass containing a nanometer scale native oxide film is studied in the present work using an atomic force microscope. The internal structure was characterized by transmission electron microscopy while the surface oxide layer was tested by X-ray photoemission spectroscopy. The alloy showed surface elastic stiffening on thermal cycling in liquid nitrogen which relaxed in 2 days. The obtained results are discussed in comparison with the bulk metallic glasses studied earlier.
