Mechanical robustness plays an important role in the manufacturing and assembling processes as well as reliable operation for thermoelectric devices. Herein, we first give a detailed study on the mechanical properties of nanostructured α-MgAgSb. The corresponding Young's modulus, nanoindentation hardness, compressive strength, and fracture toughness are 55.0 GPa, 3.3 GPa, 389.6 MPa, and 1.1 MPa m1/2, respectively, which have a close relationship with the intricate microstructure. Compared with other p-type thermoelectric materials, the good mechanical properties of nanostructured α-MgAgSb further highlight the realistic prospect for power generation.
