due to the galvanic effect of Mg matrix coupled with second phase particles. Key words: MB8 magnesium alloy; second phases; filiform corrosion; saline immersion; corrosion 变形镁合金具备非常优良的综合力学性能,可通过塑性变形和热... corroded region behind. The second phases show significant effect on the propagation of filiform corrosion. The filiform corrosion grows in all directions due to the dispersively distributed second phases......

. The equilibrium phase constituents could not be obtained at room temperature by hammering. This is mainly because the hitting force is larger and the energy obtained by alloy particles mainly makes the alloy.... And the combined results made the metastable phase not transform into the equilibrium phases, i.e. the equilibrium phase at room temperature cannot be obtained. The small balls and particles, the particles......
microstructures along the thickness. The precipitate behavior of the second phase particles and their effects on the distribution of dislocations and layered recrystallized grain structure were analyzed... related to the size and distribution of the second phase particles during PSN, the aim of the present work is to study the formation mechanism of the layered grain structure in 01420 Al-Li alloy......
with α2-Ti3Al and γ-TiAl when the alloy was annealed at 900℃, while Ti3AlC reaches equilibrium with α-Ti and γ-TiAl at 1250℃. In α2+γ phase field, TiC+Ti3AlC dual phase structure particles in as cast alloy change into thin elongated plate Ti3AlC. When the composite was annealed in α+γ phase field, the dual phase structure particles change into single phase blocky and lath-like Ti3AlC particles, and TiC......
