Researchers solve 100-year-old metallurgy puzzle

Posted by in category: materials


To solve a 100-year puzzle in metallurgy about why single crystals show staged hardening while others don’t, Lawrence Livermore National Laboratory (LLNL) scientists took it down to the atomistic level.

The research appears in the Oct. 5 edition of Nature Materials.

For millennia, humans have exploited the natural property of metals to become stronger or harden when mechanically deformed. Ultimately rooted in the motion of dislocations, mechanisms of metal hardening have remained in the crosshairs of physical metallurgists for more than a century.
