For a steel alloy it has been determined that a carburizing heat treatment of 10 h duration at 753°C will raise the carbon concentration to 0.50 wt% at a point 3.3 mm from the surface. Estimate the time necessary to achieve the same concentration at a 5.6 mm position for an identical steel and at a carburizing temperature of 1060°C. Assume that D0 is 3.2 × 10-5 m2/s and Qd is 104 kJ/mol.
