A diffusion couple of two metals, A and B, was fashioned as shown: Diffusion of of A-B altoy Diffusion of Baton After a 33-hour heat treatment at 1060°C (and subsequent cooling to room temperature), the concentration of A is 3.2 wt% at the 15.3-mm position within metal B. If another heat treatment is conducted on an identical diffusion couple, this time at 870°C for 33 hours, at what position will the composition be 3.2 wt% A? The preexponential and activation energy values for the diffusion of Ain Bare 4.7 x 105 m²/s and 137 kJ/mol, respectively. mm
