THERMAL-EXPANSION OF WHISKERS OF TI(C,N) SOLID-SOLUTIONS

In this investigation we present results of lattice parameter measurem ents of whiskers and needle-like crystals of TiNx,TiCx and Ti (C,N) so lid solutions of varying composition. Precise values of the lattice pa rameters were determined for the temperature range 293-600 K. For the stoichiometric crystals the real values were obtained by introducing d ifferent corrections of systematic errors. The thermal expansion coeff icients in the whole range of TiN-TiC compositions were determined and also a polynomial fitting alpha = f[C/C + N] is given. (C) 1998 Elsev ier Science S.A.
