原位生成Mo-Ni-Si提升Mo-Re合金/AlN陶瓷钎焊接头力学性能
In-Situ Generated Mo-Ni-Si Phase Strengthens the Mechanical Proper-ties of Mo-Re Alloy/AlN Ceramic Brazed Joints
摘要
Abstract
With the rapid advancement of modern electronics technology,high-density heat dissipation demands in critical applications impose stringent requirements on packaging materials.High-reliability joint components made from Mo-Re al-loy and AlN ceramic can effectively meet the needs of high-temperature and extremely complex working conditions.In this study,the joining of Mo-Re alloy and AlN ceramic was successfully achieved using a Ni-based multi-principal element braz-ing filler.The effects of holding time on microstructural evolution and mechanical properties of the joint were investigated.Benefiting from the in-situ formed Mo-Ni-Si ternary phase within the joint,residual stresses were effectively relieved.Un-der the process parameters of 1100℃/45 min,the room-temperature shear strength of the joint reached 111 MPa,and the high-temperature shear strength at 1000℃was 62 MPa,respectively.This study provides a novel approach for achieving high-reliability,high-quality connections between Mo-Re and AlN,and the joints with excellent high-temperature mechani-cal properties are expected to expand the applications in extreme-environment electronic packaging..关键词
