Nickel 200 alloy is being considered for use in a reactor that is meant to withstand creep damage at 925 degrees C. Calculate the strain that is put on the nickel 200 alloy as it is heated up from 25 degrees C to 925 degrees C. Assuming that the deformation is completely elastic, compute the amount of stress that is put on the nickel 200 alloy. Use values of Yield Stress, Ultimate Tensile Strength, Coefficient of Thermal Expansion and E for nickel 200 alloy.
