    EFFECT OF HEAT TREATMENT CONDITION ON CRACK TOUGHNESS AND CRACK PROPAGATION RATE OF 2.25Cr1Mo STEEL

    • The effect of different heat treatment technologies on crack toughness(KJIC) and crack propagation rate (da/dN) of 2.25Cr1Mo steel are introduced. On the base of analysis,the conclusion is made that the KJIC value is raised and da/dN has no clearly change after 730 ℃ tempering temperature.
