  • In this paper, in view of the difference of physical and chemical properties between tantalum and steel,which is easy to produce brittle intermetallic compounds during welding, resulting in poor performance and cracks of fusion welded joints. According to the idea of high entropy technology of nugget metal, a new type of interlayer alloy Ta20Fe20Ni20Cr20Co20 was designed based on the first principles of thermodynamics based on density functional theory. Combined with fusion ratio, the composition of intermediate layer alloy suitable for tantalum/steel energy storage welding is Ta7Ni32Cr19Co42. The button alloy ingot was melted by vacuum arc furnace, and then the middle alloy foil was prepared by single roll quenching method, which was used for energy storage welding connection of Ta1/0Cr18Ni9 sheet. The results show that under the condition of energy storage welding, Ta1/Ta7Ni32Cr19Co42/0Cr18Ni9 lap joint has formed a flat spherical nugget with regular and complete morphology and about 0.8 mm long diameter, and the nugget has shifted to the steel side as a whole.The nugget structure consists of simple FCC solid solution and no intermetallic compound precipitation. It has typical characteristics of high entropy alloy and realizes high entropy of nugget metal. The average strength of Ta/Ta7Ni32Cr19Co42/0Cr18Ni9 energy storage welding joint can reach 395 MPa under the welding voltage of 1 000 V, capacitance of 500 μF and electrode pressure of 30 N.
