Abstract

The crystallization characteristics of melt-quenched (MO) NiP amorphous alloys were studied for phosphorus contents ranging from 16.5 at.% to 21.0 at.% by differential scanning calorimetry (DSC) and by thermomagnetic analysis (TMA). The overall crystallization scheme of MQ NiP alloys was found to be similar to that obtained previously for electrodeposited (ED) NiP alloys. However, it was found that for amorphous NiP alloys with P ??? 19.5 at.%, the first transformation temperature (precipitation of nickel) differs markedly for ED and MQ alloys owing to the different chemical inhomogeneities introduced by the preparation techniques. The appearance of such chemical inhomogeneities upon annealing well below the crystallization could be sensitively detected by magnetic measurements.
