Abstract

Pulsed magnetic field-induced motion of single twin boundaries in Ni-Mn-Ga 5M martensite has been studied using laser vibrometry technique. Maximum actuation velocities of 0.25 m/s for Type I and 2 m/s for Type II twin boundary motion were directly observed, which corresponds to velocities of 4.2 m/s and 33 m/s for these types of twin boundaries moving inside the crystal. Actuation response time of 2 μs and actuating acceleration of about 2 × 10⁵ m/s² for Type II boundary were achieved. The difference between Type I and Type II boundaries and the limiting role of inertia in twin boundary motion are discussed.
