“…The effect of cold-rolling, heat treatment and various loading conditions on the damping capacity in TiNi-based alloys has been intensively investigated [5][6][7]. Yoshida co-workers [8,9] studied the damping of TiNi and TiNiCu alloys with different composition and heat treatment.…”

“…This study highlights that the presence of the R-phase is due to cycling. A lot of studies reveal that temperatures of each transition phase (Ms, Mf, As and Af) and the peak temperatures (Mp and Ap) were influenced by the heat treatment [10,17,19,25,26]. As the heat treatment, cyclic loading is now an important parameter which can disturb the phase transformation temperatures and may be at the origin of the intermediate phase (R-phase).…”

“…The low-temperature, stress-free phase is called martensite (Mphase), which has a lower symmetry based on a monoclinic structure (B19'). In some special situations, there is an intermediate rhombohedral phase, distortion of the B2 phase, known as the R-phase [6,10,17,[19][20][21][22][23]. Presence, or not, of this last phase is strongly influenced by heat treatment of the shape memory alloy [21,22,24].…”

“…SMAs are fascinating materials which present properties that usually do not characterize ordinary metals and alloys. Indeed, TiNi shape memory alloys exhibit very specific thermomechanical behaviours, including shape memory effect [3,5,6], good superelasticity [7][8][9] and high damping capacity at room temperature [5,10,11]. Many engineering applications have been developed using some of these properties.…”

Deformation mechanisms governing the cyclic stress-strain behaviour of a TiNi shape memory alloy are investigated in this work. In order to understand the implementation of these mechanisms during cyclic loading, three low cycle fatigue tests were performed and stopped at different stages. The first test was stopped after the first cycle, the second one after 40 cycles corresponding to the beginning of the stabilization of the cyclic strain-stress behaviour and the last one was carried out up to failure (3324 cycles). Submitted to fatigue loading, the response of the TiNi shape memory alloy presents a classical pseudoelastic response. Two deformation mechanisms, identified by TEM observations, are highlighted, the first one by twins and the second by dislocation slip and their interaction with precipitates. These two mechanisms evolve without competition during cyclic loading. In the same time, nanomechanical properties were also examined and an evolution of the microhardness or indentation modulus has been noticed.

“…IF is related to the interface movement of martensitic plate variants and twin boundaries [12] and to the presence of dislocation and their interactions with other lattice defects [13]. Damping characteristics may be influenced by chemical composition [14], heat treatment [15] and processing histories [16,17].…”

Cu-Zn-Al shape memory alloys (SMAs) were analysed in two different processing states: (i) hot-forged and (ii) hot-rolled. Both hot-forged and hot-rolled specimens were cut into lamellar configuration, before being homogenized (1073 K/ 18 ks/ water) and tempered (373, 473, 573, 673 K/ 300 s/ water). From each of the five differently treated lamellas, in hot-forged and hot-rolled states, rectangular specimens were cut for dynamic mechanical analysis (DMA). The remaining segments were sectioned into metallographic specimens. The metallographic specimens were embedded into could mounting resin, ground, polished and etched for scanning electron microscopy (SEM) -observations. DMA results revealed the influence of plastic deformation procedure and heat treatment temperature on the reversible martensitic transformation.
