Consider a hypothetical material that has a grain diameter of 2.1 ( 10-2 mm. After a heat treatment at 600(C for 3 h, the grain diameter has increased to 7.2 ( 10-2 mm. Compute the grain diameter when a specimen of this same original material (i.e., d0 = 2.1 ( 10-2 mm) is heated for 1.7 h at 600(C. Assume the n grain diameter exponent has a value of 2?
