A pure iron beam is surface hardened by exposure to a carbon source at 700 degrees Celsius. At this temperature iron is in the BCC form and will dissolve (interstitial) carbon up to about 0.001 wt%. If the criterion is that the carbon concentration equals 0.0002 wt% carbon at a depth of 100 microns, how long must the exposure be?
Atoms of different elements also have different sizes, just like kernels and marbles. Use the atomic radii given below to answer the following questions. Remember that the volume of a sphere is 4/3 × ? × radius3.
