Internal Friction Behaviors of TiNi Shape Memory Alloy Fiber/Ni Matrix Composite

The objective of present work is to investigate the internal friction behavior of TiNi shape memory alloy fiber/Ni matrix composite. The TiNi fiber/Ni matrix composite was fabricated by an electroplating method using TiNi alloy fiber as the cathode and Ni plate as the anode. The internal friction as functions of temperature and strain amplitude was measured respectively. The results showed that the internal friction peaks of the TiNi/Ni matrix composites, which due to the martensitic reverse transformation of the TiNi fiber, broadened with increasing prestrain level. There was a sharp internal friction increment at the high temperature, which due to thermal expansion mismatch between the TiNi fiber and Ni matrix and recovery stress generated. Contrast to the pure TiNi alloys, the internal friction background of the TiNi/Ni composites increased with increasing temperature. Furthermore, the internal friction of the TiNi/Ni composites decreased with increasing strain amplitude measured.

In this paper, epoxy matrix composite beams with embedded TiNi (SMA: Shape Memory Alloy) fiber are applied to enhance the strength and fracture toughness of the machinery components. It is also well known that SMA shows the remarkable changes of stiffness and damping ratio between martensite at lower temperature and austenite at high temperature. A shape recovery force is associated with inverse phase transformation of SMA. The effects of heating with current and pre-strain in TiNi fiber of SMA on vibration characteristics are experimentally investigated. The active vibration control is achieved by controlling the current and pre-strain.

The temperature and field dependences of internal friction and Young´s modulus are studied using a high-resolution ultrasonic (90 kHz) technique in stoichiometric ferromagnetic Ni2MnGa shape memory alloy close to the premartensitic transformation temperature, TPM, in the demagnetized state and under moderate fields. Several new effects observed like an apparent Young´s modulus softening close to TPM under moderate fields, instead of the hardening outside this range, as well as existing controversies in the apparent elastic and anelastic properties of Ni2MnGa close to TPM are explained by microeddy and macroeddy current relaxations that to date have been disregarded.
