  • Defects and Distortion in Heat-Treated Parts

    heat treatment provides a very poor impact strength and almost completely intergranu- lar fracture surface after impact failure. This phenomenon is termed burning. Burn- ing thus occurs at a higher temperature than overheating. If this occurs during forging the forging will often break during cooling or subsequent heat treatment (Ref 4).
