通过室温下的三点弯曲试验，研究了TiX型二元和三元化合物的相对延展性，其中X为Fe、Ni、Co或它们的组合。这些研究的一般结果表明，TiFe或TiCo与TiNi形成连续系列的固溶体，条件是钛的浓度保持在50原子%。二元化合物的塑性按TiFe、TiCo、TiNi的顺序增加。此外，镍添加到TiFe和TiCo增加它们的相对延展性。这些延展性变化可以与随着镍浓度增加而增加的电子原子比相关。反过来，增加的电子与原子比被认为表明化合物的键合中越来越多的金属特征。这一结论与X射线晶格参数测量结果一致。
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.
