1. , for the production of a method for Ni-Ti rolled products, it comprises:

  • To be more than or equal at the temperature of 500 DEG C heat forged Ni-Ti alloy ingot to produce Ni-Ti alloy blank;

    Roll described Ni-Ti alloy blank to produce Ni-Ti alloy workpiece being more than or equal to hot pin at the temperature of 500 DEG C;

    At lower than the temperature of 500 DEG C by the cold drawing of described Ni-Ti alloy workpiece to produce Ni-Ti alloy rod;

    WithBe in the HIP stove operated under 700 DEG C to the temperature within the scope of 1000 DEG C and the pressure within the scope of 3,000psi to 50,000psi, by described cold worked Ni-Ti alloy rod hot isostatic pressing compacting at least 0.25 hour.
