Abstract

In this report, mechanism of grain boundary liquation was investigated by high temperature microscope.
The results indicated that (1) temperature of grain boundary liquation by increasing heating rate was lower than solidus temperature (2) grain boundary liquation was closely related to melting of inclusion.
