Strain Relaxation in Cu-Al-Ni Shape Memory Alloys Studied by in Situ Neutron Diffraction Experiments
(American Institute of Physics, 2019-02-28)
In situ neutron diffraction is used to study the strain relaxation on a single crystal and other powdered Cu-Al-Ni shape memory alloys (SMAs) around martensitic transformation temperatures. This work is focused on the ...
Ultrahigh Superelastic Damping at the Nano-Scale: a Robust Phenomenon to Improve Smart MEMS Devices
(Elsevier, 2019-03)
Micro and nano pillars of Copper-based shape memory alloys (SMAs) with feature sizes between about 2 mu m and 250 nm are known to exhibit ultra-high mechanical damping due to the nucleation and motion of stress-induced ...
