摘要：

采用电子背散射衍射（EBSD）技术对铝合金/超高强钢等离子弧熔-钎焊接头界面的组织构成、晶粒取向和取向差分布、晶粒尺寸、织构情况进行了研究。结果表明：铝合金/超高强钢等离子弧熔-钎焊接头界面组织呈明显的双层结构，由Fe4Al13相和Fe2Al5相组成，两相在晶粒尺寸和形态上存在明显差异。Fe4Al13相呈细小的等轴晶形态，以大角度晶界为主，Fe2Al5相呈柱状晶形态，以小角度晶界为主。Fe4Al13相的晶粒尺寸明显小于Fe2Al5相晶粒尺寸。Fe4Al13相的主要织构为<010>丝织构，Fe2Al5相晶粒具有明显的择优取向，其主要织构为 <001>丝织构。

Abstract:

The technique electron backscatter diffraction was used to investigate the microstructure， grain orientation， grain size and texture of the interface intermetallic compound of aluminum alloy/ultrahigh-strength steel plasma arc welding-brazing joint. The results indicated that the interface zone exhibited an obvious double-layer structure with different sizes and morphologies， which is composed of Fe4Al13 phase and Fe2Al5 phase. The Fe4Al13 phase has fine equiaxed grains morphology and is dominated by high-angle one， while the Fe2Al5 phase has columnar grains morphology and is dominated by low-angle grain boundary. The grain size of Fe4Al13 is obviously smaller than that of Fe2Al5. The main texture of Fe4Al13 phase is <010> silk texture， while the main texture of Fe2Al5 phase is <001> silk texture with obvious preferred orientation.

Key words: metallic materials, aluminum alloy/ultrahigh-strength steel, plasma arc welding-brazing, microstructure of interface, texture, electron backscattered diffraction
