Abstract
The transformations in Ti-Nb-H system containing up to 30 at.% Nb and 25 at.% H were studied by methods of X-ray, transmission electronic mi croscopy and thermal analysis. It was found that introduction of hydro en contributes to displacement of existence borders with different ph ase composition to the smaller contents of niobium and eliminated the fields with omega-phase. It was shown that the complex hydride (TiNb)H -alpha having the BCT-lattice and forming as per the eutectoid mechani sm can be formed in the system. The metastable diagram was made of pha se composition of Ti-Nb-H system as-quenching. Copyright (C) 1997 Publ ished by Elsevier Science Ltd on behalf of International Association f or Hydrogen Energy.
