ss/Zr(Cr,Mn)2/Zr2(Co,Cu,Ni,Fe)+Zr2(Ag,Cu)+Zr(Cr,Mn)2/Zr，接頭的平均抗剪切強度最高可達103.1 MPa。隨著釬焊溫度的升高或保溫時間的增加，擴散反應(yīng)區(qū)內(nèi)的富Cr基固溶體層和Zr(Cr,Mn)2層厚度增厚，釬縫中心區(qū)內(nèi)Zr2(Co,Cu,Ni,Fe)相和Zr(Cr,Mn)2相含量增多，Zr2(Ag,Cu)相所占比例減小。最后，分析了接頭的失效機制，在剪切力的作用下，隨著釬焊溫度和保溫時間的增加，接頭的斷裂位置從擴散反應(yīng)區(qū)的Zr(Cr,Mn)2層轉(zhuǎn)移到釬縫中心區(qū)的Zr2(Co,Cu,Ni,Fe)脆性相斷裂。;AgCu filler was used to braze Zr and CoCrFeMnNi high-entropy alloy (HEA). The effects of brazing temperature and holding time on the microstructure and mechanical properties of the joints were analyzed. The results show that the typical microstructure of the joints brazed at 850 ℃ for 10 min is HEA/Crss/Zr(Cr,Mn)2/Zr2(Co,Cu,Ni,Fe)+Zr2(Ag,Cu)+Zr(Cr,Mn)2/Zr. The joints have the maximum shear strength of 103.1 MPa. As the brazing temperature or holding time rises, the thickness of Cr-rich solid solution and Zr(Cr,Mn)2 layer are increased, the content of Zr2(Co,Cu,Ni,Fe) and Zr(Cr,Mn)2 phase is increased whereas the content of Zr2(Ag,Cu) phase is decreased. Finally, the failure mechanism of the joint was analyzed. Under the action of shear force, as the brazing temperature or holding time rises, the fracture position of the joint shifts from the Zr(Cr, Mn)2 layer to the Zr2(Co, Cu, Ni, Fe) phase fracture in the center of the brazing seam."/>
