Sintering kinetics of finely divided molybdenum-copper composites

  • Published:
Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

The highest activity in solid- and liquid-phase sintering was exhibited by the specimens from the mixtures with the matrix-type distribution of the copper relative to the molybdenum and a low-melting-point component content of 40%. The specimens from the industrial powders exhibited no volume shrinkage during solid-phase sintering. In these specimens zonal segregation and ruptures between individual blocks were observed. A nonuniform structure formed in the pseudoalloys affected their liquid-phase sintering and inhibited free regrouping. After low-temperature (1150°C) liquid-phase sintering a solid pseudoalloy could be obtained only at a low-melting-point component content of 40 wt.%.
