During carburization of a steel at 950 °C, carbon concentration is measured as 0.8 wt.% at a depth of 0.3 mm after one hour. The time required to get the same c...

For self-diffusion in polycrystalline copper with a lattice diffusion coefficient DL, grain boundary diffusion coefficient DGB, and surface diffusion coefficien...

The concentration C of a solute (in units of atoms-mm3) in a solid along x direction (for x>0) follows the expression C=a1x2+a2x where x is in mm, a1 and a2 are...
