7. In the binary diffusion couple illustrated below at 950C (expressed in wt% ), determine, using Do=7.4e7cm2/sec and Q=156.4kJ/mol for Al diffusion in Ti, a) What will the concentration be at the interface, assuming the erf solution {cclow)/(chi clow)=1/2[1erf(z)] is suitable? b) How much time it will take for the concentration of Al at 1m to the right to be 3% ? c) At this time what will the concentration be 5m from each side of the interface
