Abstract The morphology and feature of hot cracks in liquid forged steel flat frangeshave been observed. Once the cracks occur, they will propagate throguh 4 stages, and revealthemselves obviously as 4 featured zones. The growth of the hot cracks seems to be depen-dent upon certain technological factors, such as: liquid steel quality, solidification and stressedstate on workpieces, etc.

Key words: liquid forging steel flat flange hot crack
