The Dynamic Impact Behavior of Ti50Ni47Fe3 Shape Memory Alloys
Static and dynamic mechanical behavior of Ti50Ni47Fe3 shape memory alloy was investigated by mechanical tensile test and instrumention impact test under a wide temperature range from -196°C to 20°C. The instrumention impact test was carried out under different temperatures at which the alloys are with martensite, austenite and R phase, respectively. It is found that the alloy with austenite performed the best ductility, the samples with martensite and R phase exhibit superior and inferior ductility, respectively.
