Ahypothetical metal alloy has a grain diameter of 1.7 ´ 10-2 mm. after a heat treatment at 450°c for 250 min the grain diameter has increased to 4.5 ´ 10-2 mm. compute the time required for a specimen of this same material (i. e., d0 = 1.7 ´ 10-2 mm) to achieve a grain diameter of 8.7 ´ 10-2 mm while being heated at 450°c. assume the n grain diameter exponent has a value of 2.1.
