In the present work, the comparative study is made between Rh3AxB1-x and in Rh3BxA1-x (A=V,Nb,Ta; B=Ti) (where x= 0, 0.125, 0.25, 0.75, 0.875, 1) materials. Here, the Rh3V, Rh3Nb and Rh3Ta are taken as parent compounds and the ternary alloy addition is made by titanium with vanadium, niobium and tantalum. Electronic, elastic and mechanical properties are calculated for these compounds and the ductile/brittle analysis are made by using G/B ratio, Cauchy pressure and Poisson’s ratio. Result shows that the following alloy combinations such that Rh3Ti0.875V0.125, Rh3Ti0.25Nb0.75 and Rh3Ti0.125Ta0.875 are more ductile than their other respective combinations. All the calculated properties of Rh3Tix(V/Nb/Ta)1-x compounds are compared with Rh3(V/Nb/Ta)xTi1-x. By the way of detailed comparison we have entrenched that the existence of pronounced ductility in Rh3Ti0.875V0.125, Rh3Ti0.25Nb0.75 and Rh3Ti0.125Ta0.875 combinations. This study is extended with calculating thermal properties such as Debye temperature, melting temperature and Grüneisen parameter and anisotropy factor, cohesive energy.
