Re-examination of martensitic stabilization in Cu-based shape memory alloys Part I. Identification of occurrence stage and degree of martensitic stabilization in CuZnAl alloys

Larger Recovery Strains in Cast Fe–Mn–Si‐Based Shape Memory Alloys by Reducing Thermal Activation and Optimizing Mn Content

“…The SME was evaluated by a conventional bending test. [26,27] The specimens with 1.0 mm or 1.5 mm thickness were bent around molds with different radius (R m ) to 180°for applying a specific amount of pre-strain to the specimen at RT or 77 K. After unloading, their elastic angle θ e were measured (Figure 3a). Then, the bent samples were recovered by annealing at 873 K for 3 min, and then the recovered angle θ r were measured at RT (Figure 3b).…”

Corrosion Behavior of the Cu24Zn5Al Alloy in Sodium Sulfate Solution in the Presence of 1-Phenyl-5-mercaptotetrazole

“…CuZnAl is one of the first shape memory alloys (SMAs) based on copper, which has found its commercial application [1]; for example, the devices of fire-preventing systems in underground pit, the damper for reducing vibration [2], fluid fitting system [3], automotive industry [4], various applications in engineering fields [5][6][7]. The primary benefit of CuZ-nAl alloys is that they can be produced using conventional metallurgical methods from relatively low-cost metals, which makes them more affordable compared to commercial shape memory alloys (SMAs) [8][9][10][11]. The transformation temperature of the binary alloy is typically too elevated for practical applications, and a third element (Zn) is usually incorporated to create a useful alloy [12].…”
