The variation of the critical current density Jc of PbMo6S8 and SnMo6S8 monofilamentary wires with external transverse compressive stress σt and axial tensile stress σa at 22 and 13.5 T, respectively, is reported. Varying the reinforcing steel content in the wire matrix, different axial stress states of the filament were obtained: compressive, tensile and unstressed. The observed variation of both, Jc vs. σa and Jc vs. σt is significantly smaller compared with that of Nb3Sn wires, which is explained by the higher upper critical magnetic field Bc2 of the Chevrel phase. After the appropriate steel reinforcement, a reversible strain range up to 0.6–0.8 % (with 0.2 % compressive prestrain of the filament) is obtained, which fulfills the requirements for future technical applications of this kind of wire materials.
