A planned extrusion operation involves cold-rolled steel at 1000°C to diameter of 75 mm with Tength 65 mm and a final length 70 mm Two presses, one with capacity (extrusion force) or 30 MIN and the other with a capacity (extrusion force) of 20 MN, are available for the operation. Is the smaller press sufficient for this operation? K"=35x10*3 N [Hint: Calculate the extrusion force and compare it to the available two presses)

A compression test is performed on a 2” diameter by 5” long bar of an unknown metal. At the end of the compression test, the bar has a height of 3.5 inches. The strength coefficient (K) and the work hardening coefficient (n ) are 250 MPa and 0.4, respectively. State all assumptions needed to work the problem. a) Calculate the final diameter of the bar in inches. b) Calculate the flow stress in MPa when the length of the bar is 4”.

If the bar is reduced by extruding and the deformation efficiency is 70%, what is the extrusion pressure?
A company produces aluminum alloy billets with dimensions of 250mm diameter and 500 mm length by transforming into another aluminium alloy cylindrical block with dimensions of 200 mm diameter and 781 mm length through a powerful hydraulic press. Assume only homogeneous deformation is considered and the yield stress at hot working temperature is 40 MN/m², determine the forging force of the press required.
A upset forging operation is performed in an open die. The initial size of the workpart is: Do = 63 mm, and ho = 100 mm. The part is upset to a diameter = 70 mm.
