Abstract:
1. A method of manufacturing a sputtering target for producing a metallic glass membrane, comprising the steps of sintering atomized powder having an average grain size of 50 μm or less and having a metallic glass composition of a ternary or more alloy system with one or more metal elements selected from a group consisting of Pd, Zr, Fe, Co, Cu and Ni as its main constituent element or elements, the main constituent element or elements including a main component that is a component of greatest atomic % of the composition and the ternary or more alloy system being selected from the group consisting of Zr—Al—Ni—Cu, Pd—Cu—Si, Cu—Zr—Ti, Co—Al—B, Fe—Zr—B, Pd—Cu—Si, Ni—Nb—Zr, and Ni—Ta—Zr, said sintering step being conducted at a temperature between a glass transition point temperature and a crystallization temperature of the composition, and producing a sputtering target from the sintered body of atomized powder such that the sputtering target has an amorphous structure characterized by containing dispersed crystallites having an average size as measured by XRD (X-ray diffraction) of 10 Å to 200 Å.
