Abstract
For the production of Ni-Mn-Ga single crystalline actuator elements dicing technology was applied. In the paper results are presented for the optimized fabrication of Ni-Mn-Ga single crystalline actuator elements using dicing temperature of 80°C. The surface of single crystalline Ni-Mn-Ga actuator elements after the dicing process was investigated. A relation was found between processing parameters and quality of cutting edges. The results are discussed with respect to surface roughness, deformation layer and twinning behavior and will help to better understand the microstructure-property relationship of this new class of smart materials.
