7.Discuss briefly the deformation behavior of a structural material such as an aluminum alloy at room temperature and elevated temperature (at T >0.5 Tm where Tm is the melting point of the material). What important design parameters would you use to qualify such an alloy for room and elevated temperature applications?. b) In a laboratory creep experiment at 1000C, a steady state creep rate of 5 x 10-1% per hour is obtained. The activation energy for creep for this alloy is known to be 200kJ/mol. Predict the creep rate at a service temperature of 600C.
