Using the diffusivity determined in Prob. 12.5, and the error function equation associated with this problem, write a computer program to determine the composition of the specimen as a function of the time at a point 2x18-4m from the weld surface, and on the side of the couple with the starting composition ?Na= 0.245. Determine this composition by varying the time form 3 to 70 hours in 2?hour intervals. Plot your result in a curve of composition versus time. What is the significance of the composition limit that is approached at long times?
What will be an ideal response?
