A hypothetical metal alloy has a grain diameter of 2.4 x 10-2 mm. After a heat treatment at 575°C for 500 min, the grain diameter has increased to 9.0 × 10-2 mm. Compute the time required for a specimen of this same material (i.e., do = 2.4 x 10-2 mm) to achieve a grain diameter of 5.5 × 10-2 mm while being heated at 575°C. Assume the n grain diameter exponent has a value of 2.2.

The band in the figure below is stainless steel (coefficient of linear expansion = 17.3 ✕ 10−6°C−1; Young's modulus = 18 ✕ 1010 N/m2). It is essentially circular with an initial mean radius of 5.4 mm, a height of 4.4 mm, and a thickness of 0.51 mm.
