By examining the as-cast samples by optical microscopy, X-ray diffraction and energy-dispersive spectrometry in a scanning electron microscope, the crystal structures and chemical compositions of the primary phases and two-phase aggregates have been by: The liquidus curve for the system Nb 2 O 5-TiO 2 has been determined by means of the Griffin-Telin hot-stage microscope. The shape of the curve confirms the existence of the compounds 5Nb 2 O TiO 2 and Nb 2 O 2, which melt congruently at ° and °C, respectively.. The existence of a compound with the composition 3 Nb 2 O TiO 2 is also indicated. It melts congruently at Cited by: INTRODUCTION A re-examination of phase equilibria in the system CaO-Ti02 was prompted by results of experiments conducted in the system CaO-NbaOs-TiOa. Phase equilibrium relationships in the system CaO-NbaOg-TiOa were studied, in the first instance, with a Griffin-Telin hot-stage microscope1 equipped with a Pt/5%Rh vs. Pt/20%Rh thermocouple for the determination of the Cited by: The methods of metallographic, thermographic, x-ray diffraction, and microhardness analyses were used for studying alloys of the system titanium-copper in the concentration range 20– at. % Cu. On the basis of the results obtained and literature data, the phase diagram of the system Ti-Cu was plotted.

phase transition.[13] The ab initio phonon band structure calculations have revealed the phonon instabilities on K 8Si 46 and other materials while the phase transition happened under high pressure.[17,18] The EuO with NaCl-type structure undergone an isostructural phase transition at near 30 GPa and became CsCl-type structure at about 40 GPa.[16].

Initial examination of the collected data is an important next step to determine the type of the collected evidence and locate any other cloud services which may be linked to the device/service being examined. If data is collected in an abstract method, the examination phase is used to reconstruct the data for use with traditional forensic analysis tools.

In a Bureau of Mines study of the Ti-TiN phase system, solid single-phase regions were formed at various temperatures by interdiffusing Ti and TiN. The diffusion profiles were examined quantitatively by scanning them with an electron microprobe analyzer. An introduction Analysis Capabilities T Time (s) 0 1m 2m 3m 4m 6m 7m 8m 9m 10m Vosc(V) A number of analysis can be performed on the circuit; DC, AC, transient, Fourier and noise. There are more specific analysis available within these categories. Shown here is a transient analysis made on the Wein-bridge oscillator. For the system Ti Si C phase diagrams at K and at K were determined. For that purpose, several alloys and diffusion couples were equilibrated and analysed by EPMA (electron probe. A RE-EXAMINATION OF THE Ti-TiN PHASE SYSTEM INTRODUCTION Purpose This investigation was prompted by puzzlement about some as-pects of the behavior of nitrided titanium, observed in attempting to apply published phase diagrams to practical situations over a period of several years. It was decided that the time had come for.
