3) A tensile test is performed to determine the parameters strength constant C and strain- rate sensitivity exponent m for a certain metal. The temperature at which the test is performed = 500°C. At a strain rate = 10/s, the stress is measured at 140 MPa; and at a strain rate = 150/s, the stress = 280 MPa. (a) Determine C and m. (b) If the temperature were 600°C, what changes would you expect in the values of C and m?
