Pseudoelasticity in an Fe–28Mn–6Si–5Cr shape memory alloy

Design Concept and Applications of Fe–Mn–Si-Based Alloys—from Shape-Memory to Seismic Response Control

“…However, depending on chemical composition and deformation conditions, the Fe MnSi-based alloys show a relatively large and non-linear spring-back on unloading that is addressed as a partial pseudo-elasticity. 58,59) Especially, the recovery strain on unloading reaches the maximum value in the vicinity of the reverse martensitic transformation finish, A f , temperature, which suggests that the non-linear spring-back phenomenon during the unloading is a kind of transformation pseudoelasticity.…”

Tensile properties of a Fe-32Mn-6Si shape memory alloy

“…It is well known that shape memory alloys (SMA) are a particular class o f materials that can recover a memorized shape by simple heating. This remarkable property, called the shape memory effect (SME), can be exploited in the design o f original applications able to bring interesting answers to problems encountered in various industrial fields.In addition to the classical non ferrous alloys (Ni-Ti-and Cu-based alloys), iron-based SMA have attracted much attention recently due to their low cost, high mechanical strength and good formability [1][2][3][4][5][6][7].In Fe-M n-Si-based shape memory alloys system, the parent phase, face centred cubic austenite (y), transforms to hexagonal (g) martensite by the formation and overlap of stacking faults. The martensite can be reversed to parent austenite on annealing, and this imparts the SME [1,2].…”

Characteristic Structural Changes in Stress-Induced Martensitic Transformation and Reverse Transformation of a Polycrystalline Fe-Mn-Si Alloy

“…In order to understand the deformation mechanism of FeMn-Si shape memory alloys, in which the stress-induced transformation of the austenitic matrix phase to an martensitic " phase occurs, their mechanical properties [11][12][13] and microstructures [14][15][16] were investigated. In those studies, the crystallographic orientations of the matrix phase and " phase have been studied using transmission electron microscopy and scanning electron microscopy with electron backscattered diffraction, and a model was discussed in order to explain the to " phase transformation.…”
