hot-cracking-sensitivityThe design engineer already determines the tendencyof a part to be sensitive to hot cracking. This applies toboth raw part production and the operating behavior.Cracks in closed ringlugsEdge cracks at the transition to the bladeEdge cracks atthe transition tothe shroudLongitudinal cracksin the transition tothe shroudIntegral cast turbinestator annulusEdge crackinto the bladeEdge crack into the shroudGrain orientationpromotes crackformation- Restricted shrinkage and strain- Cross-section jumps- Notches- Unfavorable structural orientation
