Effects of grain size and texture on damping properties of Cu–Al–Mn-based shape memory alloys

Effect of Ce addition on the microstructure and damping properties of Cu–Al–Mn shape memory alloys

“…Several pioneering works have demonstrated that some characteristics such as superelasticity, shape memory effect and the damping properties in Cu-Al-Mnbased SMAs can be enhanced by the addition of alloying elements [6]. Sutou et al [7] have reported that the addition of B, Ni, Si can reduce the grain size obviously. They also investigated the effects of grain size on the damping properties and found that grain size was very important for enhancement of the damping and mechanical properties.…”

The Effect of Heat Treatment on the Microstructure and Mechanical Properties of Cu-Al-Mn Shape Memory Alloy

“…The enhanced ductility (elongation and reduction in area) of the alloy can result in improved workability of the alloy, and thus can be useful for practical application. Tensile strengths of the alloy are higher for 60-130 MPa than those obtained for the same alloy in research Sotou et al 15 By ageing at 200 °C and 300 °C, the tensile strength is significantly increased, while the plasticity of the alloy is very low (below 2 %). The highest tensile strength is obtained after aging at 300 °C (1002 MPa).…”

Damping Properties of Arc Ion Plating NiCrAlY Coating with Vacuum Annealing

“…The enhancement of the annealing temperature can lead to the increase of grain size and the refinement of the coating surface obviously, this is proved by the surface morphology of the coatings annealed at 1173 K and 1273 K in Figure 5. Research has shown that the increase in grain size is not conducive to the improvement of the coating damping performance [25].…”
