對1060鋁板進行了攪拌摩擦加工(FSP), 通過在加工區添加鈦粉的方法原位生成了第二相Al3Ti顆粒, 研究了第二相顆粒的分布及焊核區晶粒尺寸。
鋁板攪拌摩擦加工后原位自生第二相顆粒及焊核區晶粒尺寸In-Situ Produced Second Phase Particles and Grain Size in Weld Nugget Zone of Aluminum Plate after Friction Stir Processing對1060鋁板進行了攪拌摩擦加工(FSP), 通過在加工區添加鈦粉的方法原位生成了第二相Al3Ti顆粒, 研究了第二相顆粒的分布及焊核區晶粒尺寸。結果表明: 在焊核區前進側鈦粉的彌散程度隨FSP道次的增多而增大, 4道次后基本呈彌散分布, 并與鋁反應生成納米級Al3Ti顆粒, 該顆粒從界面處剝落后仍聚集于鈦粉周圍; 第二相顆粒有效地限制了晶粒的長大, 其數量較多的區域晶粒較細小, 且在加工后熱處理中幾乎不發生長大。
The friction stir processing (FSP) was performed on 1060-Al plates, and the Ti powders were added into the processing zone to in-situ produce the second phase particles of Al3Ti. The distributions of the second phase particles and the grains in the weld nugget zone were studied. The results show that at the advancing side of the weld nugget zone, the dispersity of Ti powders increased with the FSP passes increase and after 4-pass FSP reached a homogeneous state. Ti powders were reacted with Al and the nano-scale Al3Ti particles were obtained. The particles were peeled off from the interface but still aggregated around Ti powders. The second phase particles can inhibit the grain growth effectively. The more amounts of the second phase particles in the area, the finer grains were obtained and the grains almost did not grow during the heat treatment after processing.
