Define temperature iron is in the bcc form and will dissolve

Reference no: EM13506534

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?
