Not really. Armor made of this material has to be much thicker than ordinary steel plate. Furthermore, ordinary steel plate is entirely effective against swords, except at the joints and articulations.
Against the immediate cutting, probably. But it also bends. And with bending, it could damage you really bad, including the part that removing them could become quite a trouble.
True, but cutting is what we're talking about here, and since the material they've invented in this article is made of aluminum foam, it'll bend even easier than steel of the same thickness.
