X-Ray and Neutron Diffraction with Amorphous Ti

The amorphous alloys Ti 6 7 Si 3 3 , V 6 7Si 3 3 , and Cr , 7 Si 3 3 were produced by sputtering. Their structure was investigated by X-ray and neutron diffraction. X-ray diffraction showed that the structure of the three metallic glasses is not isomorphous. Neutron diffraction showed that S i -S i atomic pairs occur preferentially with distances distinctly larger than the atomic diameter of the Si atoms. For T 6 7 Si 3 3 partial pair correlation functions could be evaluated from combination of the X-ray and the neutron data. The structural results are compared with the structure of amorphous M n 7 4 S i 2 3 P 3 .
