A diffusion couple of two metals, A and B, was fashioned asshown:
After a 730 hour heat treatment at 1060°C theconcentration of A is 3.1 wt% at the 3.1 mmposition within Metal B. At what temperature (in Kelvin) must thediffusion couple need to be heated to produce this sameconcentration at a 1.7 mm position after 730 h?The preexponential and activation energy values for the diffusionof A in B are 3.5 × 10-5 m2/sand 244 kJ/mol, respectively.
