About this technology
Overview
Researchers at the NASA Glenn Research Center have developed a new family of shape memory alloys that are strengthened by incorporating ceramic or refractory nanoparticles into the alloy. The resulting material is referred to as a shape memory metal matrix composite or SM3C. The new dispersion-strengthened metals retain the useful properties of the shape memory alloy without the typical deficiencies. Specifically, the dispersoids improve the material’s dimensional and thermal stability while increasing both the creep resistance and hardness. The SM3C material is compatible with multiple manufacturing processes including additive manufacturing , mechanical alloying, or other conventional processes like melting and extrusion. Parts produced using the SM3C may be used in various aerospace, marine, or automotive applications as actuators or in the biomedical field as surgical tools and orthopedic implants.
