本研究探討了利用摩擦攪拌製程(Friction Stir Processing, FSP)及添加強化材來改善A5083鋁合金。透過鎢極惰性氣體電弧銲(TIG)方法，將ER5356和純銅線作為強化材料，將板材和強化材料加熱並熔入凹槽中。隨後，進行FSP製程使強化材料達到強化鋁合金的效果。並在室溫環境下，對其形貌、組織結構、硬度和耐腐蝕性進行了分析。在添加銅線強化材的情況下，透過X-ray圖譜分析，確認了母材和熱影響區(Heat Affected Zone, HAZ)中存在Al、Al_6(Mn,Fe)和Mg_2 Si相。在攪拌區中，組織結構發現大量的Al_4 Cu_9及銅顆粒。前進端的熱機影響區(Thermo Mechanically Affected Zone, TMAZ)中觀察到具有網狀結構的Al_2 CuMg相。後退端的TMAZ主要由Al_4 Cu_9和Al_6(Mn,Fe)的顆粒狀結構組成，均勻分散在α-Al基底中。而添加ER5356強化材，攪拌區中的粗大Al_6(Mn,Fe)顆粒破碎，並形成了細小的顆粒(小於10 µm)。HAZ區域富含Mg_2 Si和Al_6(Mn,Fe)，與母材中的結構相似。此外，在TMAZ區域中仍觀察到些許Mg_2 Si相，並且發現Al_6(Mn,Fe)相也從粗大變為細小顆粒狀。添加ER5356強化材的試片，其耐腐蝕性較母材有所提高。相比之下，添加銅線強化材的樣品具有更高的腐蝕電流密度，故耐腐蝕性較母材差。由於在銅線強化材試片中存在Al_4 Cu_9金屬間化合物，使攪拌區及TMAZ的硬度比HAZ及母材更高。HAZ沒有承受任何塑性變形，僅受到了熱影響，因此導致該區域的硬度降低。使用ER5356強化材的試片硬度稍有提高，可能是由於攪拌區和TMAZ中的劇烈塑性變形。顯微組織觀察到HAZ區域有細小的Mg_2 Si析出物均勻分佈在鋁基底中，因此硬度比母材更高。.

520 3 $a This study investigated the friction stir processing (FSP) with a groove filling to modify A5083 aluminum alloy. The sheets and filler metals were heated and melted on the groove surface by tungsten inert gas welding with the ER5356 and pure copper wires. Then, using the FSP method, aluminum plates reinforced with filler metal had been fabricated. After holding at room temperature, the morphology, microstructure, microhardness and corrosion resistance were analyzed. In the case of reinforced with copper filler, based on X-ray diffraction peaks the presence of Al phase, Al_6(Mn,Fe) and Mg_2 Si were confirmed in base metals and heat affected zone (HAZ). Microstructure in the stirred zone exhibited a large amount of Al_4 Cu_9 and copper particles. The Al_2 CuMg phase appeared as like net structure was observed in the thermo-mechanically affected zone (TMAZ) of advance side. TMAZ of retreat side were mainly granular structures of Al_4 Cu_9 and Al_6(Mn,Fe), spread evenly dispersion throughout the α-Al matrix. Compared with ER5356 filler, the coarse Al_6(Mn,Fe) particles were broken and fine particles (smaller than 10 µm) formed in stir zone. HAZ was found to be enriched with Mg_2 Si and Al_6(Mn,Fe), similar to the structure in the base metal. Besides, a part of the existing Mg_2 Si phase was observed in TMAZ, and it was exhibited that the Al_6(Mn,Fe) phase was also coarse-to-fine and spherical. The sample reinforced using filler ER5356 could be improved corrosion resistance to the base metal. In contrast, reinforced using filler copper had worse corrosion resistance than base metal due to higher corrosion current density. Due to the presence of Al_4 Cu_9 intermetallic compounds from the copper reinforced sample, the stir zone and TMAZ had higher hardness than the HAZ and base metal. The HAZ did not bear any plastic deformation and experienced only thermal effects, thus contributing to the reduced hardness in this region. A slight increase in hardness of reinforced with ER5356 filler was possibly due to intense plastic deformation in stir zone and TMAZ. Microscopic observations of the HAZ region fine precipitates of Mg_2 Si evenly distributed throughout the aluminum matrix, hence resulted in higher value of hardness than base metal..
