Abstract
On the basis of studies factors are established which reduce the level and stability of the adsorption activity of a TiFe-Ni composite such as interphase reaction of intermetallic with metal during composite sintering and the passivating effect of oxygen impurity in the metal phase. In order to reduce the effect of these factors to a minimum it is possible to recommend optimizing the amount of interphase surface in the composite and maximum refining of the metal phase with respect to oxygen.
