Driving Force for Metastable Phases

You can use chemical driving forces for metastable phases in the POP file.

Example	ED_EXP commands
To prevent BCC_A2 to be stable	CREATE_NEW_EQUILIBRIUM 1 1 CHANGE_STATUS PHASE FCC_A1 M7C3 M23C6=FIX 1 CHANGE_STATUS PHASE BCC_A2=D SET_CONDITION P=101325 T=1473 EXPERIMENT DGM(BCC)<-0.1:0.1
To promote CEMENTITE to be stable	CHANGE_STATUS PHASE BCC M7C3 GRAPHITE=FIX 1 CHANGE_STATUS PHASE CEMENTITE=DORMANT SET_CONDITION P=P0 T=973 EXPERIMENT DGM(CEM)>0.1:0.01

Example

ED_EXP commands

To prevent BCC_A2 to be stable

CREATE_NEW_EQUILIBRIUM 1 1

CHANGE_STATUS PHASE FCC_A1 M7C3 M23C6=FIX 1

CHANGE_STATUS PHASE BCC_A2=D

SET_CONDITION P=101325 T=1473

EXPERIMENT DGM(BCC)<-0.1:0.1

To promote CEMENTITE to be stable

CHANGE_STATUS PHASE BCC M7C3 GRAPHITE=FIX 1

CHANGE_STATUS PHASE CEMENTITE=DORMANT

SET_CONDITION P=P0 T=973

EXPERIMENT DGM(CEM)>0.1:0.01
