Consider a hypothetical material that has a grain diameter of 6.3 ´ 10-2 mm. after a heat treatment at 500°c for 4 h, the grain diameter has increased to 1.10 ´ 10-1 mm. compute the grain diameter when a specimen of this same original material (i. e., d0 = 6.3 ´ 10-2 mm) is heated for 5.5 h at 500°c. assume the n grain diameter exponent has a value of 2.0
