Eutectic-reaction brazing of Al0.3CoCrFeNi high-entropy alloys using Ni/Nb/Ni interlayers
文献摘要：
In this study,a novel eutectic-reaction brazing of Al0.3CoCrFeNi high-entropy alloys(HEAs)1 was investi-gated with a design of laminated Ni/Nb/Ni interlayers.The typical AI0.3CoCrFeNi brazing seam consisted of proeutectic γ,the lamellar eutectic structure composed of face-centered cubic(FCC)phase(eutecticγ)and C14 Laves,as well as a few amounts of Nb based solid solution.A high density of nanoscale ordered L12(γ')phase was precipitated within γ phase matrix.With the brazing temperature raised from 1200 to 1320℃,the dissolution volume of Al0.3CoCrFeNi alloy into Ni-Nb liquid was increased.The microstructure of the brazing seam changed from hypereutectic(blocky Laves+γ phase)to eu-tectic(Laves+eutectic y)to hypoeutectic structures(proeutectic γ+Laves/y eutectic structure).The shear strength of joints was increased gradually due to the formation of eutectic lamellae and the cellular growth of proeutectic y phase.The maximum shear strength of the joint brazed at 1320℃for 10 min was up to 592 MPa,reaching 95％of the base metal.The joint mainly ruptured in the soft proeutectic γphase in a ductile fracture mode.
