摘要
利用X射线能谱仪、俄歇电子能谱仪、金相显微镜、扫描电镜及显微硬度计对铍与HR 1不锈钢 (Be/SS)感应钎焊样品的微区成分、组织和性能进行了研究。所用铝硅钎料组织由初生α铝与AlSi共晶体构成 ,与SS及铍表面浸润良好 ,在靠近铍侧有明显的扩散过渡层 ,过渡层中存在金属间化合物。使用铝硅钎料进行感应钎焊实现Be/SS连接是可行的。
Microstructure and composition of the beryllium/st ai nless steel(00Cr17Ni14Mo_2)(Be/HR-1)brazed joint were investigated with X-r ay energy dispersive spectrometer, scanning electron microscope,auger electron spe ctrometer and optical microscope.The results indicate that the brazing material AlSi_ 12 infiltrates well to the surfaces of HR-1 stainless steel and Be.An apparent interface layer exists between the welding area and Be.The welding are a is mainly composed of α Al and AlSi phase.It is feasible to joint Be and SS with AlSi_ 12 by induction brazing.
