Parameters

Input parameters

C - real array of dimension 7
C contains the concentrations (by weight percent) of carbon, silicon, manganese, nickel, molybdenum, chromium, and vanadium.

M - real
M is the melting point (in kelvin). If it is assumed that solidification is as for delta ferrite, then a value of 1793.0 may be used.

R - real
R is the universal gas constant (in joules per mole per kelvin, Jmol-1K-1).

Output parameters

D - real array of dimension 8
D contains the concentrations (by weight percent) of carbon, silicon, manganese, nickel, molybdenum, chromium, vanadium, and iron, in the the solute depleted regions.
