Abstract:Sandvik Nanoflex (ASTM-A 564) is a metastable steel that undergoes strain induced martensitic
transformation during a mechanical deformation process. The aim of the experiments is to observe the
transformation by recording the amount of martensite via a magnetic sensor. The physics underlying
the process suggests that although transformation proceeds with plastic straining, the stress-state
should have a big influence on its rate. Additionally, the Magee theory on martensitic variants states
that transformation proceeds as different variants become energetically favorable. Hence, it remains a
question how the material will behave upon a sudden change in the imposed stress-state since the
number of favoured variants is expected to change abruptly. Therefore, making use of the biaxial
setup a series of stress states and strain paths are imposed on the material and the effects on
transformation rate are observed.
