Correlation between alloy composition of Laves-phase ZrV,\_,\_,Mn,Ni, (x = 0.2-0.8, y = 1.0, 1.2, 1.4) alloys and their negative electrode performance such as discharge capacity and high-rate dischargeability was investigated. At any y value unit cell volume decreased with increasing ratio of atomic

The effect of iron additions on the stability of various Laves phases in the Nb-Cr base system has been examined. In the binary Nb-Cr system a hexagonal (CI 4) Laves phase exists at temperatures above approximately 1860 K, and undergoes a shear-like martensitic transformation to a face centered cubi
