DEFINITION
DIFCOE specifies the diffusion coefficient for carburization of the material. EXAMPLES: The format for the DIFCOE keyword file is shown for specific examples.
Type 1 Example for Material 1

|---|---|---|
| 800 | 0.2 | 0.5 |
| 900 | 0.6 | 0.9 |
| 1000 | 0.98 | 0.89 |

Type 2 Example of Material 1
| ATOM (%) | C1 | C2 |
|---|---|---|
| 0.1 | 0.2 | 0.5 |
| 0.2 | 0.3 | 0.6 |

REMARKS
For Type 1: A is atom content and T is temperature For Type 2: C1(T) and C2(T) are coefficients as a function of temperature and A is the atom content which is extracted from the element data. For Type 3: C1(A) and C2(A) are coefficients as a function of atom content and T is temperature which is extracted from the element data. Applicable simulation types: Microstructure Module
