Notes:
The error function can be calculated based on the Simpson method through a subroutineprogram. An integration program by FORTRAN language was made for diffusion equations ofextended source with infinite extent and limited extent. The distribution curves of alloying elementscould be driven from calculated results written in ASCII code. The results on some alloyingelements such as C, Co, Cr, Mn, Mo, Ni and V’s diffusion in iron, showed the diffusion distance forNi and Mo can only be 1~3 μm and more distance for Co at common sintering temperature of1120℃. Increasing the sintering temperature up to 1300℃, distribution curve could be improved.To refine the particle size of the added elements down to a scale of micrometers is an effective wayto get homogeneous distribution
