? 2022 Elsevier B.V.The multi-phase equiatomic GaInSnZn high entropy alloy (HEA) has been synthesized via induction-melting, which exhibits similar behavior as compared to remaining room-temperature liquid metals (LMAs). This HEA, as well known as a low melting HEA, is a near-eutectic alloy with melting point around 9.08 ℃ extracted from DSC results and electrical conductivity about 4.68 MS/m at 20 ℃. The phase constituents are corroborated by theoretical calculations of the formation criteria regarding HEAs. The feasibility as a promising direct-writing inks of the flexible electronic circuits to replace several LMAs is demonstrated by a sequence of conceptual experiments and contact angle measurements. A trade-off among melting temperature, conductivity and costs superior to conventional LMAs is considered to origin from the multi-principal component concepts. This study sheds lights on the fabrication of flexible electronic circuits at low costs and may open novel insights for developing low melting point HEAs.
