| Summary: | 碩士 === 國立中央大學 === 機械工程研究所 === 97 === As the high specific strength and high corrosion resistance, aluminum alloy is well used in many industry field, ex: 3C product and auto mobile component.
Aluminum alloy have different microstructure and texture in different procedure, like rolling or extrusion processes, the dislocations bring from the procedure will disperse in different anneal condition, to following the recovery, recrystallization and grain growth, make the grain boundaries to form high angle or low angle.
Aluminum-Magnesium alloy possession a work hardening property, because of the stacking fault energy in magnesium is lower than aluminum, it’s will bind the dislocations and block to cross slip or climb, therefore, the more working ratio, the more strength.
This study using the 5052-H32 as the material, observation the relationship between substrate and AAO film in different working and annealing condition, moreover, monitoring the V-t curve to observation the AAO properties. When annealing and rolling condition changed, the film thickness and color will different, following affected the AAO film chemical composition.
