1. , a kind of method that is used for thermal treatment turbine components (10), described method comprises:

  • This turbine components is placed in the vacuum melting furnace that is designed to the limiting surface oxidation;

    Controllably heat this turbine components to prevent distortion;

    The recrystallize surface damage layer makes it to become and has at least the approximately fine grained structure of the grain size of ASTM grain fineness number 6, to prevent to produce fatigue cracking;

    AndControllably cool off this turbine components to prevent distortion.
