You have received a job ve received a job at Boeing, and asked to improve the hardness (and strength) of a steel e dy "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 -0 wt %. Using the Figure 5.11, calculate how long it would take at 1500 degree C to reach a carbon content of 0.6 wt% at a distance of 4 mm from the surface. Give answer in hour unit.
