Non-conventional alloy developmental approach targeted at incorporating intermetallics as strengtheners using thermo-physical parametric calculation and CALPHAD-based tool (ThermoCalc software) were adopted in the design of septenary non-equiatomic [Ti20Al20Cr5Nb5Ni19Cu12Co19] HEAs. Thermo-physical properties indicated a lightweight and dual-phase HEA having density of 6.22gcm-3 and 6.88 VEC value. At room temperature conditions, computation using ThermoCalc of version 2021b (TCHEA4) encrypted database shows the presence of 6 phases, where BCC_B2, FCC_L12, Sigma, Heusler and C1_Laves are pronounced at varied volume fractions with BCC_B2 occupying 69.8 vol% of the predicted HEA. Traces of O_Phase were observed, and 144.096HV was computed as the maximum predicted total hardness.
