| Abstract: | ABSTRACT The effect of stabilization processing on the normal temperature creep and low cycle fatigue resistance of high carbon patenting steel wire and low carbon HSLA steel wire is described. Experimental results show that optimal stabilization processing parameters (as 300 ℃ , 5mi、 3% plastic deformation) can decrease the normal temperature creep value and increase low cycle fatigue life. The stabilization treatment mechanism for improving normal temperature creep and low cycle fatigue resistance is discussed as well. |
