Asheet of bcc iron 4.0-mm thick was exposed to a carburizing atmosphere on one side and a decarburizing atmosphere on the other side at 725°c. after having reached steady state, the iron was quickly cooled to room temperature. the carbon concentrations at the two surfaces were determined to be 0.011 and 0.0069 wt%. calculate the diffusion coefficient if the diffusion flux is 2.9 × 10-8 kg/m2-s, given that the densities of carbon and iron are 2.25 and 7.87 g/cm3, respectively

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
