摘要：
The formation of Mo(Si,Al)(2) on Mo dipped into Al-Si liquid saturating Si were investigated, as well as Nb(Si,Al)(2) on Nb. The Mo(Si,Al)(2) layer was made of fine needlelike grains with submicrons in diameter. On the other hand, Nb(Si,Al)(2) consisted of submicron-order fine grains. Liquid phase consisting of Al-Si was observed at the grain boundary of the intermetallic layers and at the interface between the product and the refractory metals. This implies the formation of the intermetallics by solution-repricipitation process.
