Abstract
A study of the relative ductilities of binary and ternary compounds of the type TiX, where X is Fe, Ni, Co, or combinations of these, has been performed by means of three‐point bending tests at room temperature. The general results of these studies indicate that TiFe or TiCo forms a continuous series of solid solutions with TiNi, provided the concentration of titanium remains at 50 at.%. The ductility of the binary compounds increases in the order TiFe, TiCo, TiNi. Also, nickel additions to TiFe and TiCo increase their relative ductilities. These ductility changes can be correlated with the increasing electron‐to‐atom ratio as the nickel concentration is increased. In turn, the increasing electron‐to‐atom ratios are taken to indicate an increasingly metallic character in the bonding of the compounds. This conclusion is consistent with x‐ray lattice parameter measurements.This publication has 6 references indexed in Scilit:
