Experimental Investigation and Thermodynamic Description of the Li-Si-Ni Ternary System
The 150 ℃ isothermal section of Li-Si-Ni ternary system has been experimentally established.The investigation is based on X-ray powder diffraction and scanning electron microscopy techniques on about 80 ternary alloys, prepared by argon-arc melting of proper elemental ingots.The existence of six ternary compounds is conformed.Fourteen three-phase regions have been detected.Furthermore,thermodynamic description of the Li-Ni and Li-Si-Ni systems is carried out with the CALPHAD approach on the basis of the present experimental results and the first-principle calculation of the formation enthalpies for τ1 and τ3 ternary compounds.Reasonable agreement of the phase equilibria in the Li-Si-Ni ternary system between the experiment and thermodynamic calculation is achieved.
