A steel that has 0.151% C is subjected to a carburizing
treatment. Under operating conditions, the carbon content on the
surface reaches 1.1% C. The temperature at which the process is
carried out is 996 °C, where the material is FCC, (D0 = 0.23 cm2/s,
Q = 32900 Cal/mol°K, R =1.987 cal/mol).
Estimate the carbon content at a depth of 57 microns from the
surface, (1mm=1000 microns), after 7 hours of treatment.
Suppose that the function erf(Z) can be approximately evaluated
by the following equation:
erf (2) = -0.3965Z2 + 1.24952 -0.0063
