摘　　要：采用真空钎焊方法,以AlSiMg共晶合金作为钎料,对3003波导组件进行一体化连接。分析结果显示:钎缝界面处发生弥散宽化,Mg、Si元素向母材扩散,有晶间渗入现象,近缝区母材发生了再结晶。以ANSYS软件作为平台,建立铝合金波导的三维有限元模型。从真空炉均温区受热辐射升温的角度出发,对几何尺寸较小、具有复杂型腔的钎焊组件进行受热及传热的分析,通过数值模拟的方法得到波导组件温度随时间变化的分布规律。对后处理数据进行提取和分析,得到等效位移的分布云图。By the method of vacuum brazing, AlSiMg eutectic alloy was used as brazing filler metal to connect the 3003 waveguide components. The results show that the interface of the brazing seam is diffused and widened, Mg and Si elements are diffused to the base metals and intergranular infiltration occurs, and the base metal near the joint is recrystallized. ANSYS software was used as a platform to build a three-dimensional finite element model of aluminum alloy waveguide. From the point of the radiation heating in the uniform temperature zone of vacuum furnace, the heating and heat transfer of the brazed components with small geometry and complex cavity were analyzed and the temperature distribution of the waveguide components with time was obtained by numerical simulation. Then through extraction and analysis of data processing, the distribution nephogram of equivalent displacement was obtained.
