Induced-strain actuation displacements of the actuator measured by the test and predicted by magnetic analysis agreed well, and blocked forces, according to the input currents, were estimated from the testing results.
The design procedure based on the magnetic analysis is shown and finite-element calculation results are given.
Coarsening of Ni3Ge precipitates in binary Ni Ge alloys containing 12.15, 13.01 and 14.03 at.% Ge, aged at 724 °C (equilibrium volume fractions, fe, equaling 0.022, 0.105 and 0.202, respectively) was investigated using transmission electron microscopy and magnetic analysis.
The geometric, thermal and magnetic analysis leading to the coil design is discussed.
The coupling coefficient introduced in the magnetic analysis is experimentally determined and compared to previous researchers' values.
The coarsening behavior of coherent Ni3Si precipitates in six binary Ni Si alloys with Si concentrations of 10.98, 11.42, 11.74, 12.69, 13.38 and 14.35 at.% Si was investigated using transmission electron microscopy (TEM) and magnetic analysis.
To distinguish the phase transition after heat treatment, XRD analysis with characteristics (Philips Cu-Kα radiation (λ = 1.54 Å)), and magnetic analysis with device characteristics (model PAR-155), have been performed.
