   It's a bad summary. There have been strong aluminium alloys since the   
   1930's when they began to be used extensively in aircraft construction.   
      
   The particular virtue of MIT work is that it exploits 3-D printing,   
   relying on very rapid local heating to produced very small fine-grained   
   inclusions that provide very effective local reinforcement.
