- •
Addition of Zr leads to change of lattice parameters of B19′ martensite phase.
- •
The phase transition path on heating and cooling was changed by Zr content.
- •
Yielding behavior is related to evolution of twinning mode in martensite plate.
- •
Correlation between structural evolution and deformation behavior was studied.
- •
Structural evolution during deformation was the key to decide yielding behavior.
