At approximately what temperature (in Kelvin) would a specimen of an alloy have to be carburized for 1.8 h to produce the same diffusion result as at 930°C for 14 h? Assume that values for D0 and Qd are 2.8 × 10-4 m2/s and 137 kJ/mol, respectively.At approximately what temperature (in Kelvin) would a specimen of an alloy have to be carburized for 1.8 h to produce the same diffusion result as at 930°C for 14 h?
