X-RAY-INVESTIGATIONS ON MOLTEN BI-PB ALLOYS

Using X-ray diffraction, structure factors and pair correlation functi ons of molten Bi-Pb alloys were determined. As well the calculated Deb ye temperatures as the partial pair correlation functions obtained wit h the concentration method indicate that alterations of the short rang e order due to a reduction of unlike atomic pairs with rising temperat ure take place. Moreover, the properties of the melt dependent on temp erature can be explained ii the existence of associates like the perit ectically melting epsilon-phase is assumed.
