Mass Transfer of High-Temperature Alloys in Lead,

Abstract

The relative resistance to mass transfer in liquid lead of 21 metals and alloys has been measured. Tests were performed in small quartz thermal convection loops. The test temperature was about 800 deg C with a thermal gradient of 300 deg C existing across the loops. Of the metals and alloys studied, only columbium and molybdenum exhibited a high resistance to mass transfer. Nickel and nickel-rich alloys were highly susceptible to mass transfer. Evidence is presented to show that alloys in which a tendency toward intermetallic compound formation exists show a higher resistance to mass transfer in liquid lead then do their pure metal components.
