Abstract
Electromigration induces the flux of metal elements and causes separation of the elements in an alloy. Electromigration also possibly induces the recrystallization of metal. Nevertheless, no experimental evidence has been reported for such recrystallization behavior. We report the observation of recrystallization of dispersed Zn second phases in Sn–9Zn alloy. The Zn polycrystal of aged Sn–9Zn alloy recrystallizes under electromigration to form a thin prism sheet crystal of basal plane unit with (0001) preferred orientation.
