| Abstract: | According to the driving test results and the failure analysis of the tank track pans of medium Mn cast steel, shot peening was proposed as the pre-strengthening measure. In this paper analyses the microstructure and the strengthening characteristics of the hardened layer and investigates the influences of shot peening on the fatigue crack growing on linking ribs of track pans. The results show that shot peening is an effective way to prolong the overall service life of track pans. |
