Development and Thermal Properties of Cu-Mo Composite Materials

We have developed a Cu-Mo composite material with high thermal conductivity by liquid-phase sintering of mixed Cu and Mo powders. A planetary ball mill has been used to mix the powders. Degree of mixing in sintered samples is estimated to know its effect on thermal conductivity. Strong correlation b...

Zusammenfassung:	We have developed a Cu-Mo composite material with high thermal conductivity by liquid-phase sintering of mixed Cu and Mo powders. A planetary ball mill has been used to mix the powders. Degree of mixing in sintered samples is estimated to know its effect on thermal conductivity. Strong correlation between degree of mixing and thermal conductivity is observed. It is found that homogeneity of mixing and high density are required to produce a composite with high thermal conductivity.
