This book was released on 1965 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: A complete phase diagram of the system molybdenum-carbon is presented. A thermodynamic model for the description of the phase separations of the Me2C phases in transition metal-carbon systems has been developed and was semiquantitatively applied to Mo2C. Literature data on thermodynamic properties of molybdenum carbides have been critically evaluated and data were selected. Apparative techniques for the precise study of phase reactions at high temperatures are described.

Rudy and published by . This book was released on 1967 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: The binary alloy system molybdenum-carbon was investigated by means of X-ray, metallographic, thermoanalytical, and melting point techniques on chemically analyzed specimens. The system is characterized by three congruently melting, intermediate phases, Mo2C, Eta-MoC(1-x), and Alpha-MoC(1-x), of which only Mo2C is stable at temperatures below 1650 C. Substoichiometric (is greater than 32.5 At% C) dimolybdenum carbide undergoes a homogeneous sublattice order-disorder transformation at temperatures of approximately 1400 C, whereas hyperstoichiometric compositions undergo a discontinuous phase-change. The order-disorder transitions in the Me2C phases are discussed in terms of the structural changes involved in the transformation processes and the absence of long range sublattice coherency in stoichiometric or hyperstoichiometric compositions attributed to the impossibility of obtaining long range order in a linear chain of alternating carbon atoms and vacancies. From the experimental phase relationships and the known thermodynamic data for Mo2C, limits for the free energies of formation for the high temperature phases Eta-MoC(1-x) and Alpha-MoC(1-x) are derived and found to be in good agreement with data previously obtained from phase equilibria in ternary metal-carbon systems.

Rudy and published by . This book was released on 1965 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: The alloy system tantalum-carbon was investigated by means of X-ray, DTA, and melting point techniques on heat-treated and chemically analyzed alloys; a complete phase diagram was established. Analogously to the findings in the Ta-C systems, a previously unknown phase reaction of the Nb2C phase was found to occur at high temperatures. The melting temperatures of the monocarbide phase and the NbC-C eutectic reaction isotherm were redetermined. The alpha- beta-Me2C-phase reaction could not be found in the vanadium-carbon system.
