- •
CPFEM revealed the effect of the kinematic stability of the γ phase on the phase-transformation.
- •
A phase-transformation model was implemented in the CPFEM to consider TRIP behaviors in DSS.
- •
α΄and γ in the deformed sample shows the Kurdjumov-Sachs (K–S) relationship.
- •
The individual flow curves of the α, γ and α′ phases in DSS were determined via in-situ neutron diffraction in combination with the CPFEM.
- •
CPFEM revealed the effect of the kinematic stability of γ on the number of activated α΄-variants.
