℃ and 495 ℃, and the ordinary burnt phenomena of the ingots between 480 ℃ and 495 ℃ does not occur because the excess low-melting point eutectic phases in the as-cast alloy dissolve into the matrix during... increases with decreasing of heating rate for homogenization treatment of the ingot. In the as-cast alloy, there is a lot of eutectic products along grain boundary and interdendrite, whose melting......
