B1. Consider a hypothetical material that has a grain diameter of 2.0x10 mm. After a heat treatment at 550C for 4 h, the grain diameter has increased to 8.0 x102 mm. Compute the time required for a specimen of this same original material (do = 2.0x10 mm) to achieve a grain diameter of 5.5x102 at 550C. Assume the n (grain diameter exponent) has a value of 2.2
