A Zr58.5Nb2.8Cu15.6Ni12.8Al10.3 (Vitreloy 106a) bulk metallic glass (BMG) was successfully welded by friction stir welding (FSW) with a fixed polycrystalline cubic boron nitride (PCBN) pin tool below its crystallization temperature. The microstructure was analyzed by X-ray diffraction (XRD) to evaluate the crystallization of the weld. The reduced radial distribution function (RDF), short-range order (SRO) domain size, and atomic pair distribution function (PDF) were analyzed to evaluate the effect of FSW at atomic scale. As a result, the SRO domain size was reduced for the weld surface, while increased for the weld nugget.
