STRUCTURE OF AMORPHOUS Pt_(60)Pb_(20)Sb_(20) WITH SPLIT FIRST X-RAY HALO

摘要

The split in first X-ray halo observed in metallic glass Pt_(60)Pt_(60)Sb_(60) indicates phase separation. However, the sharpness of the first peak in g(r) does not support phase separation. The first interatomic distance, coordination number CN and the shoulder on the second peak in g(r), -all these together support the Bernal's hard sphere random packing model.
