Extrusion/Die Practical 018 PR Die Performance Optimization through Understanding of the Surface Features of Fatigue Fractures Pawel Kazanowski -- Hydro Aluminum Cedar Tools, USA Die failure analysis guides design improvements, materials selection, operating procedures, and components use. Macroscopic fracture surface appearance associated with known loading conditions is emphasized. Fracture surface shows force type and direction acting on a die, force magnitude and fluctuations, and time from initiation to final fracture. Case studies examine real failures. Findings assist in tool steel selection and extrusion die manufacturing processes. |
