Influence of the Substitution of Chromium for Manganese on the Structure and Hydrogen-Sorption Properties of Ti.sub.47.5Zr.sub.30Mn.sub.22.5 Eutectic Alloy

Influence of the Substitution of Chromium for Manganese on the Structure and Hydrogen-Sorption Properties of Ti.sub.47.5Zr.sub.30Mn.sub.22.5 Eutectic Alloy

We study the influence of alloying with chromium on the structure and phase composition of the Ti.sub.47.5Zr.sub.30Mn.sub.22.5 eutectic alloy and its hydrogen sorption-desorption. It is shown that the addition of chromium to the alloy changes the type of crystal lattice of the Laves phase from the C...

Zusammenfassung:We study the influence of alloying with chromium on the structure and phase composition of the Ti.sub.47.5Zr.sub.30Mn.sub.22.5 eutectic alloy and its hydrogen sorption-desorption. It is shown that the addition of chromium to the alloy changes the type of crystal lattice of the Laves phase from the C14 hexagonal phase to the C15 cubic, which does not affect the hydrogen-sorption properties. It is demonstrated that hydrides obtained on the basis of the C14 and C15 Laves phases have different thermal stabilities.
