Bonus Problem (worth 5 extra points.) You must show all your work to receive credit! 27. 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 (No need to use Error Function), calculate how long it would take at 1500 degree C to reach a carbon content of 0.4 wt % at a distance of...

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...

QUESTION 18 1 points Save Answer Consider the Hall-Herault process for aluminum extraction. Aluminum ore Al203 melts at 935°C and forms eutectic mixture of NaF and AlF3. Once aluminum is in the melt in ionic form (Al), electrolysis is performed, in the presence of oxygen, using carbon anode. Anode reacts during the electrolysis and has to be replaced. Calculate the standard cell voltage in V from thermodynamic data. (2A1203 + 3 ? ? 4 AI + 3 CO2). Express using...
