Abstract
Melting and solidification of a Pb-Sn eutectic alloy have been observed dir ectly using an in situ heating experiment in a high-voltage electron micros cope (HVEM). Melting takes place preferentially at a Pb/Sn interface and gr ain boundaries of Pb and Sn. Solidification takes place very quickly and th e resultant eutectic microstructure changes drastically during subsequent c ooling. It has been found that, at high temperature, grain boundaries of Pb and Sn are segregated with Sn and Pb, respectively.
