| Abstract: | The initial melting process of laves phase of GH4169 alloy at different heating rates has been observed in situ by confocal laser scanning microscope.The relationship between the heating rate and the initial melting temperature of laves phase has been studied.The suitable range of heating rate in the first stage homogenization process is 5~10℃/min,which provides scientific reference for production. |
