  • Mechanical testing to determine Young's modulus, yield strength, and plastic strain.

    • Main Results:

    • The alloys possess a composite microstructure with dendritic beta-Ti(M) phase in a nanocrystalline matrix.
    • Achieved a low Young's modulus ranging from 59-103 GPa.
    • Exhibited high yield strength between 1037-1755 MPa with significant plastic deformation.

    Conclusions:

    • The developed Ti(60)Cu(14)Ni(12)Sn(4)M(10) alloys demonstrate a favorable combination of high strength and low elastic modulus.
    • These properties suggest significant potential for use as advanced biomaterials in medical implants.
    • Further research is warranted to explore their long-term performance and biocompatibility in vivo.
