چکیده انگلیسی
An NiTi alloy was produced by twin roll casting technique. Microstructure, thermal behaviour, texture and shape recovery were studied by optical microscopy, differential scanning calorimetry (DSC), X-ray diffraction and elongation measurements. The strip reveals a relatively large thermal hysteresis loop (almost 70°), which is characteristic for the martensitic transformation course B2 â B19â². The crystallization front which simultaneously proceeds from the outer part of the strip to its centre causes a preferential orientation of the growing grains. In consequence, a texture is formed as a mixture of the fibre ã0 0 1ã orientation and the sheet texture component {0 0 1}ã1 0 0ã. The strip shows a good shape recovery with the recoverable elongation of 3.5%.
