| 中文摘要: |
| Au-12Ge共晶合金传统生产工艺操作复杂，重复性差，成品率低。本文采用一体式加工工艺，制备出厚度为20 μm的箔材钎料。采用扫描电子显微镜(SEM)研究Au-12Ge共晶合金铸态、不同轧制变形量的显微组织形貌，采用同步热分析仪(DSC)研究Au-12Ge箔材的共晶转变温度。结果表明，Au-12Ge共晶合金的铸态组织为Au相和Ge相，随着热轧变形量的增大，Au-12Ge共晶合金组织Ge相经历细化分散到粗化过程，粗大的Ge晶粒内部包裹软质的Au相；Au-12Ge共晶合金箔材的熔点为361℃。 |
| 英文摘要: |
| The traditional production process of Au-12Ge eutectic alloy is complicated, with poor repeatability and low yield. In this paper, an integrated processing technology is used to prepare Au-12Ge foil brazing material with a thickness of 20 μm. The microstructure and composition of as-cast and different rolling deformations of Au-12Ge alloy were studied by scanning electron microscopy (SEM). The eutectic transition temperature of Au-12Ge foil was tested by a synchronous thermal analyzer (DSC). The results show that the as-cast microstructure of Au-12Ge eutectic alloy consists of Au phase and Ge phase. With the increase of hot rolling deformation, the Ge phase of Au-12Ge eutectic alloy undergoes the process of refining, dispersing to coarsening, and the soft Au phase is encapsulated within the coarse Ge grains. The melting point of Au-12Ge eutectic alloy foil is 361℃. |
