摘要:	本計畫的實驗材料為AA6061、6066和6082鋁合金擠製棒材，不同棒材經由退火後，取0-40%變形量作深冷鍛造、常溫鍛造及熱鍛造，鍛後試棒執行析出強化T6熱處理。不同試棒探討變形對材料微結構變化及試片表面陽極膜品質的影響，並調查封孔後鋁合金的抗腐蝕性。近幾年來，深冷變形對鋁合金的晶粒細化的影響已引起學術界的重視，並了解到深冷變形有助於減小晶粒尺寸或形成奈米級晶粒，進而增加鋁合金的強度和韌性。另外，由於電動汽車的開發受到業界相當的重視，因此在汽車輕量化的需求下將使鍛造鋁合金的應用範圍更廣泛。然而，深冷變形對鋁合金的機械性質和耐腐蝕能力的影響…等資料尚未完全建立；業界大多數是以熱鍛造來生產機件；而且現有文獻較少探討變形後的鋁合金陽極行為與陽極皮膜品質的差異；因此，本計畫的執行可提供不同變形溫度及變形量對鋁鎂矽銅合金微結構和機械性質的影響，以及陽極皮膜和耐腐蝕性的影響資料數據和分析。 ;This study will prepare extruded bars of AA6061, AA6066 and AA6082 aluminum alloy. These extruded bars are subjected to cryo-forging, cold-forging and hot-forging after annealing, then subsequently doing artificially aging to obtain samples. Effects of deformation on varying microstructure, anodizing behavior and corrosion resistance of tested samples will be studied, and corrosion resistance after hot water sealing also included. In recent years, industries are interested on applying cryogenic deformation to alter microstructure of aluminum alloys to reduce grain size, corresponding to increase strength and toughness of aluminum alloys. Moreover, weight reduction in automobile industry becomes an urgent challenge for improving fuel efficiency. Therefore, the technology for developing lightweight/good toughness wrought-aluminum alloys to make automobile parts draw a great attention from industry and academics. Data-base on different degree of deformation at different temperatures of 6xxx aluminum alloys has not been well constructed. Industries commonly use hot forging process to produce forged parts. There are few research results are published to discuss effect of microstructure on the anodizing behavior and corrosion resistance of forged 6XXX alloys. The objective of this study is aiming to build up technical data including different deformation at different temperature on microstructure, mechanical properties, the anodizing film qualities and corrosion resistance of three common used 6061, 6066 and 6082 aluminum alloys.
