T02_20_FeCMn_E_GammaAlphaIsotherm_2D_Lin Alpha-Ferrite nucleates and grows from undercooled isothermal gamma-austenite grain structure in Fe-0.1 wt%C- 1wt% Mn.
Mn is modelled with NPLE (non partitioning local equilibrium). Since no cooling is applied, the growth slows down with time and the structures ripen while fractions move symptotically towards a temporary partial-equilibrium (with Mn still non-partitioned, but contributing to local driving forces).
(2D, lin. phase-dagram, isothermal)
T02_21_FeCMn_E_GammaAlphaIsotherm_2D_TQ Alpha-Ferrite nucleates and grows from undercooled isothermal gamma-austenite grain structure in Fe-0.1 wt%C- 1wt% Mn.
Mn is modelled with NPLE (non partitioning local equilibrium). Since no cooling is applied, the growth slows down with time and the structures ripen while fractions move symptotically towards a temporary partial-equilibrium (with Mn still non-partitioned, but contributing to the local driving forces).
(2D, TQ, isothermal)
T02_22_FeCMn_E_GammaAlphaIsothermPara_2D_TQ Alpha-Ferrite nucleates and grows from undercooled isothermal gamma-austenite grain structure in Fe-0.1 wt%C- 1wt% Mn.
Mn is modelled with NPLE para-equilibrium conditions. Since no cooling is applied, the growth slows down with time and the structures ripen while fractions move symptotically towards a temporary partial-equilibrium (with Mn still non-partitioned).
The simulation is identical to T02_20_FeCMn_E_Gamma_Alpha_Isotherm_Para_2D_TQ execpt for the fact that Mn is here modelled with para-equilibrium conditions, causing higher driving forces and growth rates, as Mn partitioning has no growth-restrictinge effect, i.e. is not contributing to the driving force.

The simulation is identical to T02_20_FeCMn_E_Gamma_Alpha_Isotherm_Para_2D_TQ execpt for the fact that Mn is here modelled with ParaTQ option.

T02_24_FeCMn_E_GammaAlphaCementite_2D_TQ Alpha-ferrite nucleates and grows from gamma-austenite grain structure during cooling of Fe-0.25 wt%C- 0.174 wt% Mn. Towards the end of the transition cementite nucleates on alpha-gamma interfaces.
Note: The coupled eutectoid grwoth of cementide and ferrite (pearlite) cannot properly be resolved on this 2D scale. Instead, the pearlite may be modelled as diffuse 'unresolved' region, as demonstrated in example T02_26_FeCMn_E_GammaAlphaPearliteEff_2D_TQ under same conditions.

T02_25_FeCMn_E_GammaAlphaCementite_2D_TQ+Lin Alpha-ferrite nucleates and grows from gamma-austenite grain structure during cooling of Fe-0.25 wt%C- 0.174 wt% Mn. Towards the end of the transition cementite nucleates on alpha-gamma interfaces.
In contrast to example T02_24_FeCMn_E_GammaAlphaCementite_2D_TQ, Cementite is here not taken from the database,but modelled user-defined with LinTQ.
Note: The coupled eutectoid groth of cementide and ferrite (pearlite) cannot properly be resolved on this 2D scale. Instead, the pearlite may be modelled as diffuse 'unresolved' region, as demonstrated in example T02_26_FeCMn_E_GammaAlphaPearliteEff_2D_TQ.
(2D, TQ+LinTQ, constant cooling rate)

Ferrite nucleates at austenitic grain boundaries. System is cooled down with constant heat extraction rate, while latent heat is released. Mn is not partitioning at austenite/ferrite interface (option: 'nple'). Cementite grows in eutectoid transformation together with ferrite thus forming pearlite. Pearlite is modelled as an effective phase by defining nucleation of cementite with option 'unresolved'.

A017_M247_Additive_constGV An already liquid layer of CM247LC powder (30 microns thick) is solidified under constant thermal gradient and cooling rate. The substrate consists of two initial flat grains with different orientation, leading to cellular-dendritic growth and formation of a grain boundary. As interdendritic phases gammaprime (FCC_L12#2) and MC (FCC_L12#3) are considered. Diffusion coefficients in the melt are taken from database (MOBNI5) and averaged over 10 equi-distant segments in z-direction.
A018_Al4Cu_Additive_Rosenthal An solid homogeneous layer of Al4Cu (as single fcc-phase, virtually representing the base metal plus powder layer) is heated from the top assuming thermal conditions of an (arbitrary) heat source ("Rosenthal solution"), which is applied in form of time-dependent temperature profiles (A018_Rosenthal.txt). This solid layer, which is represented by the simulation domain, is partially molten and then re-solidified. As interdendritic phase theta phase (AL2CU_C16) is forming during the solidification stage. Formation of new fcc-grains is considered only by fragmentation during melting.
