• Ni-Ti-Cu alloy
• mechanical cycling
• mechanical behaviour

In this paper was studied the influence of the mechanical cycling on mechanical behavior of a Ni-Ti-Cu alloy, having in view the number of the applied cycles and the influence of the mechanical charging on mechanical hysteresis. For mechanical cycling were varied 2 parameters: number of cycles and applied force. In experiments was used a mechanical micro-testing modulus (GATAN MicroTest 2000N), attached to a scanning electron microscope, type TESCAN - VEGA II XMU. The main conclusion is that the mechanical cycling at higher loading-unloading levels has as result the increasing in maximum tensile strength and maximum strain to failure. For lower levels of loading-unloading the results are opposite.
