First Time

Thermal expansion of some members of the synthetic solid solution åkermanite-gehlenite was measured (in the range 25-1200°C) for the very first time, with the aim of clarifying the behaviour of this solid solution both with respect to composition and temperature. The results confirmed the non-ideal behaviour at room temperature (negative excess molar volume), and showed a different non-ideal response at high temperature. In fact, excess molar volume is different during the heating and cooling stages: for Xak<0.5 it becomes, from almost ideal, strongly positive at high temperature, while for Xak>0.5 it is always negative. It can then be inferred that (i) lattice dimensions are very sensitive to cation diffusion activated by temperature, (ii) intra-crystalline partition mechanisms, and their effects on the structural features, vary as a function of composition in the solid solution studied.

Ni Additions

Nickel is often added to cobalt-based superalloys to stabilize their austenitic structure. In this work the effects of Ni on several high temperature properties of a chromium-rich cobalt-based alloy reinforced by high fraction of TaC carbides are investigated. Different thermal analysis techniques are used: differential scanning calorimetry (DSC), thermo-mechanical analysis (TMA) and thermogravimetry (TG). Results show that the progressive addition of nickel did not induce great modifications of microstructure, refractoriness or thermal expansion. However, minor beneficial effects were noted, including reduction of the melting temperature range and slight decrease in thermal expansion coefficient. The most important improvement induced by Ni addition concerns the hot oxidation behavior. In this way, introducing several tens wt % Ni in this type of cobalt-based alloy may be recommended.
