Effect of rolling conditions on the structure and shape memory properties of Fe–Mn–Si alloys

Characterization of phases in an Fe–Mn–Si–Cr–Ni shape memory alloy processed by different thermomechanical methods

“…Previous works have demonstrated that a favourable defect structure, i.e. a high density of stacking faults and an appropriate balance of dislocations, may be controlled by applying thermomechanical treatments to a material with the appropriate chemical composition [3][4][5][6].…”

“…They found an austenite single-phase field in the temperature range of 1000°C to 1100°C and a three-phase field, consisting of austenite, δ-ferrite, and the (Fe, Mn) 3 Si intermetallic phase, above 1100°C. Within the temperature range of 700°C to 1000°C, a twophase field consisting of austenite and a Fe 5 Ni 3 Si 2 type intermetallic phase exists, and below 700°C, a single austenite phase field exists.…”

Microstructure and shape memory properties of Fe–15Mn–5Si–9Cr–5Ni melt-spun ribbons

“…Söderberg et al [12] reported that the SME can be improved by a simple process of cold rolling. More recently, Baruj and Troiani [13] and Druker et al [14] showed that a combination of rolling deformation followed by annealing produces an almost perfect SME without the necessity of introducing precipitates.…”

Thermodynamic Explanation for the Large Difference in Improving Shape Memory Effect of Fe–Mn Alloys by Co and Si Addition

“…[2] In 1986, Murakami and coworkers developed polycrystalline Fe- (28)(29)(30)(31)(32)Mn-(4-6.5)Si alloys showing almost complete SME as well. [3] In 1991, Otsuka et al developed Fe- (14)(15)(16)(17)(18)(19)(20)(21)(22)Mn-(5-6)Si- (8)(9)(10)(11)(12)Cr-(5-7)Ni alloys exhibiting good SME along with good corrosion resistance through alloying with Ni and Cr. [4] Thereafter, much research has been carried out on these Fe-Mn-Si-based alloys to further improve their recovery strain, including training, [5][6][7][8] thermo-mechanical treatment, [9][10][11] ausforming, [12,13] and precipitation of second-phase particles.…”
