Figure 5.21 shows that the analysis of the fine lamellae included both the W-rich and W-poor phases, and does not reveal any deviation from the original W-composition of the alloy. There is an abrupt change of solute concentration at the interface, consistent with the discontinuous mechanism of transformation. 

Bangwei et al. [107] studied the influence of solution variables on the electroless deposition of Ni-W-P. Using citric acid as a complexant for both Ni2+ and WO j [67], they observed maxima as a function of WO concentration in solution in the P and W contents of the deposits (Fig. 10(a)) and kinetics of electroless deposition (Fig. 10(b)) the influence of citric acid on these three quantities is shown in Figs. 10(c) and 10(d). The increase in deposition rate with WO concentration may be due to consumption, through complexation, of citrate by WO, thereby increasing the concentration of the reactive uncomplexed Ni2+ ions. An increase in deposition rate with WO4- concentration was also observed by Osaka et al. [108], The rapid decrease in P and W compositions at concentrations greater than 0.05 mol dm-3...

The coefficient of thermal expansion (CTE) of composite materials usually follows the simple rule of mixtures (or more complex models), based on the CTE of the respective components, their volume fraction and the volume fraction of interfacial phases. Based on these models, a Si3N4-Si3N4(w) composite should possess a similar CTE to monolithic Si3N4 ceramic (3.2 x 10 6/°C). obviously, the chemical composition of the sintering additive will have a certain influence but should remain within the variations observed for monolithic Si3N4. 

W/m K, the thermal conductivity of the Si3N4-SiC(w) composite can increase or decrease depending on the type of SiC whiskers added.23...

For Si3N4-Si3N4(w) composites one would not expect any significant change in elastic modulus however, as 100% solid density is rarely achieved, there may be some decrease depending on the level of porosity present.
