Two multicomponent ¢-type Zr alloys were designed using the d-electron alloy design method, and their mechanical properties, magnetic susceptibility, and Young's modulus were evaluated. A phase stability (B- oM- d) map was constructed by performing theoretical calculations and was subsequently used to determine alloy compositions (Zr14Nb5Ta1Mo and Zr14Nb10Ta1Mo mass%) based on the results previously obtained for ZrNb, ZrMo, and ZrTa ternary alloys. The designed alloys were fabricated via arc melting and casting methods. They consisted of the ¢-phase and a small volume fraction of the ½-phase. Both alloys exhibited similar mechanical properties; however, a higher strength of 796 MPa and an elongation of 15% were obtained for the Zr14Nb5Ta1Mo alloy. Furthermore, the fabricated Zr14Nb5Ta1Mo and Zr14Nb10Ta1Mo alloys were characterized by low magnetic susceptibilities of 16.96
