Effect of phosphorus concentration on the atomic distribution function of amorphous Pd-Ni-P alloys

Abstract

The effect of the phosphorus concentration on the atomic distribution function in amorphous alloys (Pd_(50)-Ni_(50))_(100−x)P_x in which x varies from 15 to 27.5 was investigated. The alloys were obtained by rapid quenching from the liquid state. The intensity of the first peak of the interference function decreases with increasing phosphorus content. The second peak has a definite shoulder on the right side for alloys low in phosphorus and this shoulder progressively disappears as the P concentration is increased. This feature was not found before in binary Ni-P alloys obtained by electrodeposition. From the atomic distribution functions it was possible to determine the metal‐to‐metal distances and the approximate metal‐to‐phosphorus distances.
