Transcribed Image Text:
A billet 75 mm long and 25 mm in diameter is to be extruded in a direct extrusion * operation with extrusion ratio rx=4. The extrude has a round cross section. The work metal has a strength coefficient K=415 MPa and strain hardening exponent n=0.18. Use the Johnson formula with a=0.8 and b=1.5 to estimate the extrusion strain. Determine the following for a remaining billet length L= 25 mm: 1. Ideal Strain & (Value and unit) 2. Extrusion strain ex (Value and unit) 3. Average flow stress Yf (Value and unit) 4, Ram pressure P (Value and unit) 5. Ram Force F (Value and unit) A billet 75 mm long and 25 mm in diameter is to be extruded in a direct extrusion * operation with extrusion ratio rx=4. The extrude has a round cross section.
