Current Attempt In Progress For a steel alloy it has been determined that a carburizing heat treatment of 17 h duration at 700'C will raise the carbon concentration to 0.39 wt at a point 3.9 mm from the surface. Estimate the time necessary to achieve the same concentration at a 7.7 mm position for an identical steel and at a carburizing temperature of 1030°C. Assume that Dois 3.1 * 10 m/s and Q, is 103 kJ/mol. e Textbook and Media...
