Ni-Mn-Ga magnetic shape memory alloy for precise high-speed actuation in micro-magneto-mechanical-systems
(Lappeenranta University of Technology, 2019-01-17)
Single crystalline Ni-Mn-Ga alloys are known for their large reversible magnetic-field-induced strain (MFIS) of several percent. This effect was discovered and named magnetic shape memory (MSM) by K. Ullakko in 1996. Since ...
Twin boundary dynamics in magnetic shape memory alloy Ni-Mn-Ga five-layered modulated martensite
(Lappeenranta University of Technology, 2018-12-10)
Ni-Mn-Ga magnetic shape memory (MSM) alloys are considered to be highly promising materials for actuation, damping, sensing and energy harvesting applications, due to the unique combination of a large transformation strain ...
Laser powder bed fusion for the manufacture of Ni-Mn-Ga magnetic shape memory alloy actuators
(Lappeenranta-Lahti University of Technology LUT, 2021-12-03)
The ability of the magnetic shape memory (MSM) alloy Ni-Mn-Ga to exhibit large magnetic-field-induced strain (MFIS) of 6-12% makes it a promising actuation material for small devices in which traditional mechanisms and ...
