  • Heat-treating method
    Patent number: 4095999
    Abstract: The present invention relates to methods for modifying the temperatures at which metallic compositions capable of undergoing reversible transformation from the austenitic state to the martensitic state will undergo such transformation. According to the present invention, the transformation temperature of such metallic compositions may be raised by slowly heating a metallic composition which is in the martensitic state to a temperature above that at which transformation to the austenitic state normally occurs. Usually the slow heating is terminated and the composition cooled to a temperature below the temperature at which slow heating was terminated.
