Consider the diffusion of some hypothetical metal Y into another hypothetical metal Z at 950°C; after 10 h the concentration at the 0.5 mm position (in metal Z) is 2.0 wt% Y. At what position will the concentration also be 2.0 wt% Y after a 17.5-h heat treatment again at 950°C? Assume preexponential and activation energy values of 4.3 × 10-4m²/s and 180,000 J/mol, respectively, for this diffusion system.
