INVESTIGATION OF RAPIDLY QUENCHED CU100-XPX ALLOYS

Rapidly quenched Cu100-xPx (x = 4.0-19.6 at%) alloy ribbons were prepa red by melt spinning. The characteristics of the alloys were investiga ted by X-ray diffraction, scanning electron microscopy and differentia l scanning calorimetry. The results indicate that rapid quenching of t he Cu-P system results in the formation of a microcrystalline structur e of alpha-Cu and Cu3P but no amorphous phase. On the other hand, rapi d quenching also leads to the supersaturated solid solution of phospho rus in alpha-Cu, and the degree of supersaturation increases with the phosphorus concentration.
