Study on the Similar Creep Behaviors and Mathematical Laws of 1Cr18Ni9Ti under Low Stress Repeated Impact

Abstract:

1Cr18Ni9Ti specimens were observed the plastic deformation by the method of coordinate grid under the low stress repeated impact test. And it found some phenomenon is similar to the creep phenomenon ,so the paper call it “repeated impact creep”. Proceeding from the theory of creep deformation, the deformation law of the specimens was analyzed and the relevant mathematical model was established.Finally, it found that the strain rate of repeated impact creep is decreased by the increase of impact times and the increase of layer’s depth.
