Scientists from Denmark (Risø National Laboratory for Sustainable Energy) have discovered a solution to the major problem of these metals which soften at high temperatures.
The nanometals are made of very small particles that make them very resistant, but these particles are unstable.
Tianbo Yu found a way to fix this structure with the addition of other particles thus opening the way to stronger and lighter materials.
Risø DTU works already on an application with aluminum in partnership with a local company.
"We are co-operating with a Danish company and also a Danish consulting engineering company with the purpose of developing light and strong aluminium materials with a view to their application in light vehicles, where deformation at a high rate, as in a collision, is in focus,’ said Dorte Juul Jensen, head of the materials research division."
