The observation of surface softening in Fe-based metallic glass
2011 (English)In: Mater. Res. Soc. Symp. Proc. Vol. 1300, Materials Research Society, 2011, 74-78 p.Conference paper (Refereed)
Depth sensing nano-indentation investigations have been performed to determine the radial dependence of the hardness through the cross section of a Fe-based bulk glassy rod. We have found the hardness of the material decreases along radius from the center to the outermost surface. This phenomenon is attributed to the ‘cooling rate induced surface softening’. Furthermore, a significant change (~15 %) in elastic modulus is noticed along the radius as well.
