, respectively. The interplane spacings are decreased after the homogenization at 580 ℃ for 240 min, and they are about 2.3328 ? for DC processed A8006 alloy and 2.3293 ? for TRC processed A8006 alloy... samples 4 Discussion A dynamic diffusion process is brought during the homogenization, as source of microsegregation on the interdendritic zones. It can produce a short-range order in the aluminium......
: The precipitation of Al3Zr particles near grain boundary was significantly different after two kinds of homogenization in the experimental Al-7.81Zn-1.62Mg-1.81Cu (AA7085) alloy. The microstructures, textures and properties of these two specimens were investigated. The results show that staged homogenization can promote Al3Zr particles precipitate in grain boundary areas. The less the Al3Zr particles......
to predict the fraction of the Laves phase dissolution. Finally, the results of diffusion coefficients indicate that the diffusion of Nb element is a critical factor for homogenization process of GH4151 alloy. Key words: GH4151 ingot; homogenization; incipient melting; Laves phase; kinetics 1 Introduction Nickel-based superalloys are important materials used to manufacture the critical components which......
