Crack Analysis of Recoil Rod |
|
|
|
Abstract Crack in back of the pole pieces, using metallographic examination, chemical analysis, hardness testing, scanning electron microscopy and other means of comprehensive analysis. Recoil rod assembly according to cracking after this phenomenon, combined with its production process and the crack initiation site characteristics of fracture morphology, analysis of recoil Cracking shot back bar for the microstructure in quenched and bad, coupled with inclusion content more, when the interference fit, by the greater stress and cracking.
