对6061-T6铝合金与AISI1018钢的摩擦焊在AS工艺条件下及随后的形变热处理进行了研究。用显微硬度图、聚焦离子束超高分辨率扫描电子显微镜和透射电子显微镜对接头进行了表征。界面金属间化合物层厚度在250~400 nm之间。这些金属间化合物在焊态时与FeAl和Fe2Al5相有关，在热机械状态下与FeAl、Fe2Al5、FeAl3和FeAl6相有关。
Friction welds between 6061-T6 aluminum alloy and AISI 1018 steel have been examined in the as process condition and following thermo-mechanical treatment. Joints were characterized by microhardness mapping, focused ion beam with ultra high resolution scanning electron microscopy and transmission electron microscopy with energy dispersive spectrum. Intermetallic layer thicknesses at the interfaces ranged from 250 to 400nm. These intermetallics appear related to the FeAl and Fe2Al5phases for as-welded condition and FeAl, Fe2Al5, FeAl3and FeAl6phases following thermo-mechanical condition.
