中温自反应钎焊铝蜂窝芯耐高温老化性能分析
Analysis on High Temperature Aging Property of Self-brazing Aluminum Honeycomb Core at Middle Temperature
摘要
Abstract
Tension‐shear test was carried out on middle temperature self‐brazing aluminum honeycomb cores after high temperature aging by micro mechanical test system ,and the microstructure and com‐ponent of the joints were observed and analyzed using scanning electron microscopy and energy disper‐sive spectroscopy to study the relationship between brazing seam microstructure ,component and high temperature aging properties .Results show that the tensile‐shear strength of aluminum honeycomb core joints brazed by 1060 aluminum foil and aluminum composite brazing plate after high temperature aging(200℃ /12h ,200℃ /24h ,200℃/36h) is similar to that of as‐welded joints ,and the weak part of the joint is the base metal which is near the brazing joint .The observation and analysis of the alumi‐num honeycomb core microstructure and component show that the component of Zn ,Sn at brazing seam is not much affected and no compound phase formed after high temperature aging ;therefore ,the main reason for good high temperature aging performance of self‐brazing aluminum honeycomb core is that no obvious change of brazing seam microstructure and component occurs .关键词
