A diffusion couple of two metals, A and B, was fashioned as shown: A-B alloy Diffusion of B ationis After a 680 hour heat treatment at 1090°C the concentration of A is 2.7 wt% at the 3.1 mm position within Metal B. At what temperature (in Kelvin) must the diffusion couple need to be heated to produce this same concentration at a 1.5 mm position after 680 h? The preexponential and activation energy values for the diffusion of A in B are 3.1 x 105 m²/s and 253 kJ/mol, respectively. Y Diffusion of Arms A
