Finally, the same in situ biaxial tensile tests were also performed with both SEM and XRD, first at low temperature in order to study the influence of temperature on the material behaviour and especially on martensite formation, and then on the same steel that was heat treated in order to increase its grain size and to study the grain size effect.
