Can you explain in your own words what the problem is asking? What is happening in the steel, and what variables does the process depend on?

i am guessing that they want me to use the graph to get another plot with concentration vs depth... then from that i am to get hardness vs depth. other than that i am confused as well. i have D and D_0 and Q_d and R and T. from this i can get concentration using flicks 2nd law.. but what about hardness and all that?

It looks to me like you're supposed to calculate the concentration as a function of depth, then determine the hardness as a function of depth based on the graph of hardness as a function of concentration.
