Khurram Yaqoob 1 AuthorId: Ici les deux sels ne sont plus semblables. Thermodynamic modeling Mo-Ni-Re Phase diagram.

Sunday, April 2, – 9: BO 3 HNa 2. Wednesday, March 27, – 6: Dites comment se comporte la composition de la phase liquide pendant le refroidissement. La solution entre alors dans la zone de cristallisation du KCl: CaAl 2 O 4.

NaOH, H 2 O. On distinguera pour simplifier deux cas: Que deviennent les courbes de solidus et de liquidus? Les courbes de liquidus, de solidus deviennent des surfaces. A B Figures En B, le chlorure de sodium cristallise. Pascal, tome XX,2, Khurram Yaqoob 1 Details. On the other hand, partial investigations of phase boundaries in the Mo-Ni and Mo-Re binary systems and determination of liquidus projection of the Mo-Ni-Re system was also carried out.


In comparison with previous investigations, the Ni-Re phase diagram determined during the present study showed significant difference in terms of homogeneity domains, freezing ranges and peritectic reaction temperature.

Par contre un refroidissement rapide ne le permet pas. The Mo-Ni-Re system is one of the important subsystems of the Ni based superalloys engineered for use in high temperature applications.

Celle-ci oxyde le zinc en ZnO. The experimental results gathered during the present study along with the information available in the literature were used as input for thermodynamic modeling of the Mo-Ni-Re system.

Quelques exemples de diagrammes ternaires. In addition, presence of two previously unknown ternary phases was also observed.


On remarque sur les figures Projection des courbes de liquidus du diagramme Pb-Bi-Sn Les courbes sont les isothermes des surfaces de liquidus: Pour en savoir plus. Le principe physique de formation est simple: Considering the contradictions among previously reported information, the present study was devoted to the complete experimental determination of the phase equilibria in the Mo-Ni-Re system, structural characterization of its intermetallic phases and thermodynamic tenraire of the system with the help of the CALPHAD method.
