摘　　要：针对QCr0.8与1Cr21Ni5Ti异种合金进行了电子束焊接技术研究。与无中间过渡层形成的焊缝相比,以Ni作为中间过渡层的QCr0.8/1Cr21Ni5Ti的电子束焊接接头,焊缝区形成了组织、成分梯度变化的过渡区,为提高QCr0.8/1Cr21Ni5Ti电子束焊接接头的力学性能提供了良好的组织保证。The microstructure of QCr0.8 and 1Cr21Ni5Ti joint by electron beam welding was analysed and investigated.Compared with the joint which formed without interlayer,the joint based Ni slice interlayer had a transition zone where the microstructures and elements distribution changed by degrees.As a result,the mechanical properties of QCr0.8 /1Cr21Ni5Ti EBW joint are improved.
