The additive produced hollow samples are in the low-temperature phase in the martensitic state at room temperature. The reversible, martensitic-austenitic phase transformation results in a shape memory effect. The additional heat treatment makes the hollow cylinders suitable for cyclic use as actuator material. Microstructure, phase transformation temperatures, and cyclic behavior were investigated. In addition, a high-load actuator element is presented.enconference paper
