Microstructure and Thermal Stability of Fe, Ti, and Ag Implanted Yttria-Stabilized Zirconia
Yttria-stabilized zirconia (YSZ) was implanted with 15 keV Fe or Ti ions up to a dose of 8 x 1016 at cm -2. The resulting "dopant" concentrations exceeded the concentrations corresponding to the equilibrium solid solubility of Fe2Oa or TiO2 in YSZ. During oxidation in air at 400 ° C, the Fe and Ti concentration in the outermost surface layer increased even further until a surface layer was form...
متن کاملMachinability of experimental Ti-Ag alloys.
This study investigated the machinability of experimental Ti-Ag alloys (5, 10, 20, and 30 mass% Ag) as a new dental titanium alloy candidate for CAD/CAM use. The alloys were slotted with a vertical milling machine and carbide square end mills under two cutting conditions. Machinability was evaluated through cutting force using a three-component force transducer fixed on the table of the milling...
متن کاملAssessment of the Al–Fe–Ti system
The Al–Fe–Ti system has been assessed and the limiting binary systems are shortly reviewed. Based on a thorough review of the literature, isotherms at 800, 900, and 1000 °C have been re-evaluated and a provisional isotherm at 1200 °C is presented for the first time. The effect of alloying the binary phases with the third component is reviewed with regard to the ternary homogeneity ranges, cryst...
متن کاملMechanical properties and microstructures of dental cast Ti-Ag and Ti-Cu alloys.
In this study, experimental Ti-Ag alloys (5, 10, and 20 mass% Ag) and Ti-Cu alloys (2, 5, and 10 mass% Cu) were made in an argon-arc melting furnace. The alloys were cast into magnesia molds using an argon gas-pressure dental casting machine, and the mechanical properties and microstructures of the castings were investigated. As the concentration of silver or copper in the alloys increased, the...
متن کاملThermodynamic modelling of the Ag-Cu-Ti ternary system
Ag-Cu-Ti system is important for brazing applications and mainly for ceramic joining. This system is characterized by numerous intermetallics in the Cu-Ti binary and the existence of a miscibility gap in the liquid phase. For applications, the knowledge of phase equilibria, invariant reactions in the temperature range of interest and thermodynamic activity values (mainly of Ti) are important. T...
