Diffusion coefficients in multiphase Ni80Cr20-Ti system

Diffusion coefficients in multiphase Ni80Cr20-Ti system

In this paper, the reactive diffusion in Ni80C20r–Ti ternary system is discussed at 1173K. The diffusion couple was prepared and annealed for 100 h. The two intermetallic phases and two two-phase zones occurred, namely: Ti2Ni, TiNi, TiNi+Cr, and TiNi3+Cr. Based on the experimental results (molar fra...
