摘要

A postprocessing strategy for Ti–6Zr–5Fe alloy with high microhardness and low Young’s modulus was developed through duplex aging. The experimental results showed that the alloy treated by solution treatment obtained the lowest microhardness (477 HV) and Young’s modulus (90 GPa). The alloy aging treated at low temperature obtained the highest microhardness (660 HV) and Young’s modulus (110 GPa). The alloy treated by duplex aging obtained an excellent combination of higher microhardness (600 HV) and lower Young’s modulus (95 GPa). The duplex aging treatment is expected to become an effective process strategy for developing similar medical Ti alloys.
