Abstract

Refinement of crystalline dendrites in a metallic glass composite, Zr56.2Ti13.8Nb5.0Cu6.9Ni5.6Be12.5, was demonstrated by friction stir processing. The surface hardness of the amorphous matrix as well as the crystalline dendritic phase was found to increase by nearly a factor of two for the processed specimens. Higher hardness for the amorphous matrix was explained by the interaction of shear bands, while that for the crystalline dendrite was explained by grain refinement.
