MARTENSITIC TRANSFORMATIONS IN NiTi POLYCRYSTALS INVESTIGATED BY IN-SITU NEUTRON DIFFRACTION

摘要

New experimental information on the deformation and transformation processes in poly-crystalline shape memory alloys can be obtained using in-situ neutron diffraction techniques. This is documented on the selected results of recent systematic neutron diffraction investigations of polycrystalline NiTi alloys transforming in thermal and mechanical cycles.
