Abstract

The quaternary system Ti-Al-C-N and its binary and ternary boundary systems are investigated using powder methods and XRD analysis. Phase equilibria at 1375 degrees C are presented in an isothermal network foralloys up to 50 at.% Ti. In the vertical section Ti2AlC1-xTi2AlN1-x acomplete series of solid solutions exists at 1495 degrees C, but a wide miscibility gap occurs at 1375 degrees C. The vertical section TI3AlC1-xTi3AlN1-x is more complex because of the occurrence of the quaternary, tetragonally distorted phase Ti3Al(C,N)(1-x) (a = 0.41135(4) nm,c = 0.41366(5) nm) and the transformation of perovskite-type Ti3AlN1-x into filled Re3B-type Ti3AlN1-x below 1200 degrees C.
