3. For a steel alloy it has been determined that a carburizing heat treatment of 10 h duration will raise the carbon concentration to 0.45 wt% at a point 2.5 mm from the surface. Estimate the time necessary to achieve the same concentration at a 5.0 mm position for an identical steel and at the same carburizing temperature. [40]

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...

2 a) It is given that a carburizing heat treatment of 10-hour duration of a steel alloy will raise the carbon content to 0.45 wt% at a point 2.5 mm away from the surface. Compute the time required to get the same concentration at a 5.0-mm position from the surface at the same carburizing temperature for an identical steel alloy (Hint: The diffusion coefficient will be a constant for two identical materials at a given temperature). b) What is the...
