Abstract
Combinatorial synthesis from elemental feedstock is a novel way to develop new alloy combinations in a time-efficient approach. In this study, laser-based combinatorial synthesis using elemental feedstock has been used to create small coupons for the Ti-based ternary alloys (Ti-Al-Nb and Ti-Ni-Cu) systems. The aim of this study is to assess the microstructural inhomogeneities of the coupons using quantitative microscopy and X-ray diffraction, and to compare the microstructure to cast alloys. It was found that the microstructural inhomogeneity, in terms of the phase fraction distribution and the chemistry, is insignificant in most alloy combinations. Post-processing heat treatment was generally not essential to obtain an assessment of the utility of the alloy combination, but it can be used to improve the microstructural homogeneity.
