STRUCTURE OF AMORPHOUS (Zr,Hf)-Fe ALLOYS
The structure of amorphous Zr 100-x Fe x and (Zr 100-y Hf y ) 76 Fe 24 alloys (22 ≤ × ≤ 40, 0 ≤ y ≤ 45) was examinated by X-ray diffraction. The calculated reduced radial distribution functions, G(r), deviate from those of typical metall-metalloid alloy glasses. Partial Zr-Zr distribution functions could be determined by varying the Fe concentration (between 22 and 28 at.%) as well as by isomorphous substitution of Zr by Hf. An unusually high packing density (74 %) of the (extrapolated) Fe-free ‘amorphous Zr matrix’ was observed.
