Abstract: 
In this report, a combination of the diffusion multiple technique and the recently developed numerical inverse method was employed for a high-throughput determination of interdiffusivity matrices in Ni-Al-Cr alloys. A face-centered cubic (fcc) quinary Ni-Al-Cr diffusion multiple at 1173 K was carefully prepared by means of the hot-pressing technique. Based on the composition profiles measured by the field emission electron probe micro analysis (FE-EPMA), the composition-dependent interdiffusivity matrices in ternary Ni-rich Ni-Al-Cr system at 1173 K were then efficiently determined using the numerical inversemethod.
