Effect of ternary addition on ductility of Rh-based intermetallics

This work presents the effect of ternary (titanium/vanadium/niobium/tantalum) addition on ductility of rhodium based binary intermetallic compounds such as Rh3Ti, Rh3V, Rh3Nb and Rh3Ta. Self-consistent band structure calculations are done on (i) Cubic Rh3BxTi(1-x) (where B = V, Nb, Ta; x= 0, 0.125, 0.25, 0.75, 0.875,1 ) (ii) Cubic Rh3BxV(1-x) (where B = Ti, Zr, Hf; x= 0, 0.125, 0.25, 0.75, 0.875, 1) (iii) Cubic Rh3BxNb(1-x) (where B = Ti, Zr, Hf; x= 0, 0.125, 0.25, 0.75, 0.875, 1) and (iv) Cubic Rh3BxTa(1-x) (where B = Ti, Zr, Hf; x= 0, 0.125, 0.25, 0.75, 0.875, 1) compounds by means of Full Potential Linearized Augmented Plane Wave(FP-LAPW) method as implemented in the WIEN2k code in order to analyze the structural, electronic, mechanical and thermal properties.
