Enhancing Mechanical Properties of Nanostructured Materials with Interfacial Films
High strength to weight material Materials exhibit no losses in ductility or high temperature stability The process can be applied to different alloys
The high strength to weight ratio make nanostructured materials ideal for military, aerospace, transportation, and construction applications
Nanostructured materials are characterized by nanometer scale crystal size. They exhibit order of magnitude higher strength versus materials with larger crystal size. However, state of the art nanostructured materials have suffered from ductility loss, as well as high temperature instability. The inventors at UCI have employed a dopant segregation technique to create a new type of crystal boundary, called an amorphous intergranular film. Nanostructured materials fabricated using this technique exhibit increased strength without sacrificing ductility and high temperature stability. The technique used to create such materials is general and applicable to many alloys.
State Of Development Laboratory scale experimental data has shown formation of nanostructured material in powder form with the improved strength/ductility/temperature resistance. Future work involves sintering the powder to form bulk samples for testing and applying Related Materials Rupert Lab Website Tech ID/UC Case 27072/2017-064-0 Related Cases 2017-064-0
