Determine the force vs reduction in height curve in open-dye forging of a cylindrical, annealed copper specifmen 10mm high and 25mm in diameter, up to a reduction of 50% for the following cases: a) no friction between the flat dies and the specimen b) u=0.10 c) u=0.30 Ignore barreling and use average pressure formulas. Then, calculate the work done and the temperature rise in the specimen for each case, assuming the process is adiabatic and and the temperature is uniform...

Hot forging is used to reduce a metallic cylindrical workpiece with a diameter of 12 cm and height of 24 cm to a height of 15 cm. The coefficient of friction of the open die plate with the workpiece is 0.18 and the process takes 4 seconds to complete and at a constant speed. The strength coefficient of the workpiece C= 180 MPa and strain rate sensitivity exponent m = 0.25. calculate the following: The forging shape factor at the...

Assume that you have two cylindrical steel samples with 1 in diameter, one made out of AISI 1045 and another one made out of AISI 4140. You austenitize and quench both samples in oil. Then you cut a section and measure the hardness at the center of each sample. Would you expect to get the same results? Explain your answer.
