Bonus Problem (worth 5 extra points.) You must show all your work to receive credit! 26. You are asked to improve the hardness (and strength) of a steel sample by "carburization" process. The initial carbon content (co) of the sample is 0.2 wt %. You are using a carbon rich environment (hydro- carbon gas) to set the surface-carbon content (c) at 1.0 wt %. Using the Figure 5.11, calculate the required carburization temperature to reach a carbon content of 0.4...
