Experimental and Thermodynamic Analysis on Phase Equilibria of Ni-rich Region in Ni-Al-Ti System

摘要

Phase equilibria including γ, γ', η, β and H in Ni-Al-Ti system were investigated by diffusion couple method and calculated with thermodynamic model. The experimental phase equilibria generally agree with ones reported till now. Regular solution and sublattice models were used in order to calculate these phase equilibria. The calculated results show agreement with experimental data.
