Question
Transcribed Image Text:Calculate the temperature at which a non-
steady-state diffusion for t=49.5 hrs was
carried out to give a carbon concentration of
0.35 wt% C in FCC of Fe, at a position 4.0 mm
below the surface, the constant concentration
at the surface of 1.0 wt% C, the initial uniform
concentration of 0.20 wt% C, a proportionality
constant independent of temperature
Do=2.3x105 m2/s, and the activation energy
Qd= 144000 J/mol. Refer to the table below,
