Phase formation by mechanical alloying in (Ti, Zr, Nb)–(Cu, Ni)–Al equiatomic alloys has been investigated. The structural features and the thermal stability were characterized by X-ray diffraction, transmission electron microscopy and differential scanning calorimetry. An amorphous phase forms when the (Ti, Zr, Nb) content is between 20 and 60 at.%. In contrast, solid solutions of Cu and (Nb, Zr) phase dominate in the final product with (Ti, Zr, Nb) content of 10 and ≥70 at.%, respectively. All amorphous phases have a large supercooled liquid region of over 125 K, indicating a high thermal stability against crystallization. Miedema's model is used to calculate the glass-forming range in this multicomponent alloy system. The calculated region coincides well with the experimental results.
