But grinding is a costly and energyintensive process. To Hart, Meroueh, and Eagar, the most promising approach — first introduced by Jonathan Slocum ScD '18 while he was working in Hart's research group — involved pretreating the solid aluminum by painting liquid metals on top and allowing them to permeate through the grain boundaries.

Aluminum is a very light metal with a specific weight of g/cm 3, about a third of that of steel. This cuts the costs of manufacturing with aluminum. Again, its use in vehicles reduces deadweight and energy consumption while increasing load capacity. This also reduces noise and improves comfort levels. Its strength can be adapted to the ...
