Mechanical And Electrical Properties

In this study, the effect of sintering temperature on the properties of tungsten-copper (W-Cu) composite produced by liquid phase sintering (LPS) process has been investigated. W-20 wt.% Cu composite powders with particle size less than 1 μm was prepared by cold compaction and followed by cold isostatic pressing. The green specimens were then sintered under nitrogen based atmosphere in the temperature range of 1100°C to 1300°C. The sintering studies were conducted to determine the extent of densification and corresponding to microstructure changes. In addition, the properties of the sintered specimens such as physical appearance, microstructure evolution, mechanical and electrical properties were presented and discussed.

Sintering Shrinkage

Frenkel?s theory of liquid-phase sintering was interpreted regarding pores as the activated component. The data of isothermal sintering shrinkage vs. time of the cordierite glass by Giess et al. are trained using the model by Nikolic et al. to obtain the relative density at varied temperatures and time. Then, the time constants are obtained as 1998.86mins, 388.21mins, 89.79mins and 26.11mins at 800?C, 820?C, 840?C and 860?C, respectively. The calculated time constants are close to that by the theoretical calculation, deviation of which arises from the fact that particle size is variable during the sintering process. The time constant determination is crucial to the research of the whole sintering process.

Particle Size Distributions

Coarsening of particles during liquid phase sintering is known to be an example of Ostwald ripening. This coarsening process, in a fully wetting system, is simulated in three dimensions with a kinetic Monte Carlo model. The results from the simulation for microstructures, kinetics and particle size distributions are compared to available experimental findings. It is found that the average particle volume increases linearly with time and that the particle size distributions are consistent with those obtained experimentally, as in the W-Ni-Fe and Sn-Pb systems.
