Preparation of ternary alloy libraries for high-throughput screening of material properties by means of thick film deposition and interdiffusion: Benefits and limitations

Abstract

Several techniques have been investigated for making alloy libraries for combinatorial materials development. In this investigation, we demonstrate a method for Ni–Fe–Cr ternary alloy library preparation by deposition of three layers of different metals with a linear thickness gradient rotated by 120° for each layer. The layers were interdiffused and alloyed by annealing in vacuum. The resulting specimens were analyzed and compared with the well-known phase diagram for this system by means of rapid x-ray diffraction mapping with synchrotron radiation.
