SCIENCE - Researchers devise a means to obtain abnormal grain growth in metal using cyclic heat treatment

(Phys.org) —A team of researchers from Tohoku University and Kyoto University in Japan has found a way to cause abnormal grain growth in metal crystals using cyclic heat treatment. In their paper published in the journal Science, the team describes how they came up with the approach, how well it works and how it might be used in future applications ...
