| Description |
The redler link in question has failed during bend test due to presence of a surface defect. Investigation showed that the defect was a lap or fold that got created during forging. This had resulted in a discontinuity in the material with a sharp root. Subsequent carburising treatment had worsened the situation resulting in a highly sensitive notch in the component surrounded by a brittle material like carburising layer. Subsequent examination confirmed that the forging defects were present in the raw material (billet) itself and got translated into the defects seen in the final products. A detailed analysis of the problem is presented in this report and the recommendations are made to prevent recurrence of similar failures.
