摘要：

Metastable monotectic Cu-50 at. % Co alloy produced by arc melting has been processed under micro gravity condition using a drop tube and subjected to differential thermal analysis (DTA). Microstructural evidence from the as solidified sample revealed that rapid cooling of the arc melt process was enough to incite liquid phase separation in the alloy. In the drop tube samples, the melting temperature of the beta-phase (Cu-rich) was determined to be 1294.8 K, whereas that of the alpha-phase (Co-rich) was found to vary with cobalt content.
