Abstract

Reliable experimental thermodynamic data are essential for the development of refractory complex concentrated alloys (RCCAs). To map such a vast compositional space, efficient high-throughput methods are required.

In this short methodological letter, we present a novel method of preparing a single sample containing multiple RCCAs compositions using blended elemental powder metallurgy (BEPM), specifically through field-assisted sintering technology (FAST). The prepared sample, with a well-defined geometry, can be subsequently used for high-throughput experimental characterization via XRD and EDS to determine the equilibrium phase content and composition for each nominal chemical composition. The viability of this methodological approach is demonstrated on a quinary Al-Ti-Nb-Zr-Ta system.

蜂窝状样品设计用于高通量制备RCCAs

可靠的实验热力学数据是研制难熔复合浓缩合金（RCCAs）的基础。要映射如此巨大的组合空间，需要高效的高通量方法。在这篇简短的方法学信函中，我们提出了一种使用混合元素粉末冶金（BEPM），特别是通过场辅助烧结技术（FAST）制备含有多种RCCAs成分的单一样品的新方法。制备的样品具有明确的几何形状，随后可通过XRD和EDS进行高通量实验表征，以确定每种标称化学成分的平衡相含量和组成。在Al-Ti-Nb-Zr-Ta五元体系上证明了该方法的可行性。
