Generic Ti-22Al-25Nb Heat Treatments


  • The samples were solution-treated at 960°C for 1 h by water quenching (WQ) and age-treated at 760° C (HT-760), 800° C (HT-800), or 840°C (HT-840) for 12 h followed by air cooling (AC).

    Vacuum hot pressing sintering was carried out at 950-1200°C with a pressure of 35 MPa for 1h followed by furnace cooling. All HP-ed (hot pressed) samples were composed of coarse equiaxed B2 grains, fine lamellar O phase inside the B2 grains, and some α2 along B2 grain boundaries.
