Abstract
The melting behaviour of alloys from Ni-rich portions of the quaternary systems Ni–Ti–Mo–C and Ni–Ti–W–C, where the monocarbide phases δ-(Ti, Mo)C and δ-(Ti, W)C coexist with metal melts, was investigated by means of differential thermal analysis (DTA), metallography, X- ray diffraction and SEM/EDS microanalysis. In a first approximation, the systems can be treated as pseudo-ternary with the components Ni–TiC–MoC and Ni–TiC–WC in the compositional range studied. Pseudo-ternary eutectic reactions: melt ⇔ Ni(ss) + δ-(Ti, Me)C + C (Me = Mo or W) have been observed and graphite can be in equilibrium with Ni(ss), δ-(Ti, Me) C and melt.
Abstract
Das Schmelzverhalten von Legierungen der nickelreichen Bereiche der Systeme Ni–Ti–Mo–C und Ni–Ti–W–C in denen die Carbidphasen δ-(Ti, Mo)C bzw. δ-(Ti, W)C mit einer Metallschmelze koexistieren, wurde mittels Differential-Thermoanalyse, Metallographie, Röntgendiffraktometrie und energiedispersiver Mikroanalyse untersucht. In erster Nöherung können diese Systeme als pseudoternör mit den Komponenten Ni–TiC–MoC bzw. Ni–TiC–WC betrachtet werden. Es wurden pseudoternöre eutektische Reaktionen Schmelze ⇔ Ni(ss) + δ-(Ti, Me) C + C (Me = Mo oder W) beobachtet. Graphit kann im Gleichgewicht mit Ni(ss), δ-(Ti, Me) C und Schmelze auftreten.
