A new dental superalloy system. 3. Microstructure and phase transformations.
A microstructural study was conducted on 15 cobalt-chromium-nickel alloys of the basic composition 40 Co-30 Ni-30 Cr. The alloys were strengthened by the addition of tantalum and tantalum-rich regions were found at the interdendritic spaces. The increase in Ta concentration caused a decrease in the concentration of the a phase and an increase in the amounts of the a phase. Excessive amounts of ...
متن کاملKinetic Pathways of Phase Transformations in Two-Phase Ti Alloys
Possible phase transformation kinetic pathways from the high temperature b phase to the low temperature (a+ b) two-phase Ti alloys were analyzed using the graphical thermodynamic method and the assumption that diffusionless and displacive transformations take place much faster than phase separation which requires long-range diffusion. It is shown that depending on the composition of a b-stabili...
متن کاملPhase transformations and segregation in Fe–Ni alloys and nanoalloys
Ordering and segregation properties of Fe–Ni alloys and nanoalloys are investigated by means of Metropolis Monte Carlo (MMC) and molecular dynamics (MD) simulations. The model is based on an embedded atom potential which, according to thermodynamic integration, only stabilizes those phases that are observed experimentally. This stability is confirmed by MMC and the same phases are found stable ...

متن کاملInternal Friction Phenomena Associated with Diffusionless Phase Transformations in Alloys
Internal friction and ultrasonic attenuation peaks associated with diffusionless phase transformations in alloys, such as thermoelastic martensites and others, were reviewed. They were discussed from the stand point of (1) Understanding the mechanism of the phase transformations and (2) Developing new alloy materials of high damping capacity for application to noise and vibration abatement. Pha...
