High-Throughput Measurement Method for Time–Temperature-Transformation Diagram of Thin Film Amorphous Alloys

Abstract

The time–temperature-transformation (TTT) diagram of amorphous alloys is important for the applications of alloys. However, measurement for it by the conventional method is a time-consuming process. We propose a high-throughput measurement method for compiling TTT diagrams of thin film amorphous alloys. For this method, a temperature gradient furnace system is used. The thin film sample is isothermally heated with a temperature gradient and monitored by thermography. Thermography can detect crystallization. Therefore, the times required for crystallization at various temperatures can be measured at once. The validity of this method is shown by comparison with the results of the conventional method.

Fulfilling the promise of the materials genome initiative with high-throughput experimental methodologies

“…7: (a) hypothesis-driven design and synthesis of a "library" sample with variations in the materials parameter(s) of interest [118][119][120][121] (typically composition); (b) rapid, local, and automated interrogation of the library for the properties of interest; 53,[122][123][124][125][126][127][128] and (c) analysis, mining, display, and curation of the resultant data. [129][130][131] Each step presents current challenges that must be overcome before HTE methodologies can be widely deployed.…”

Combinatorial and High-Throughput Screening of Materials Libraries: Review of State of the Art

“…There have been many other examples of combinatorial studies of metallic alloy systems. Among the notable developments are methodology for mapping the metallic glass and amorphous metal systems and the use of molecular beam epitaxy for fabrication of epitaxial composition spreads in search of magnetic semiconductors . These examples underscore the significance of tracking subtle structural changes across composition spread samples in pseudobinary and pseudomultinary solid solution systems.…”

Review on Quantum Mechanically Guided Design of Ultra-Strong Metallic Glasses

“…High-throughput characterization techniques have been applied for metallic glasses to investigate glass forming ability, thermoplastic formability, composition, topology, and mechanical properties. However, most high-throughput studies are purely experimental, relying on trial and error (Sakurai et al, 2007(Sakurai et al, , 2011Deng et al, 2007;Aono et al, 2010Aono et al, , 2011Guo et al, 2011;Wang et al, 2011;Ding et al, 2012Ding et al, , 2014Gregoire et al, 2012;Flores, 2014, 2016;Liu et al, 2016;Bordeenithikasem et al, 2017;Li et al, , 2019Zhang et al, 2018;Zheng et al, 2019); or empirical, such as machine learning approaches (Ren et al, 2018). In recent years, we combined ab initio calculations with high-throughput characterization techniques.…”

“…To validate the representativeness of the ab initio configuration and the properties predicted directly by ab initio calculations, a high-throughput synthesis and characterization route is required. To explore a large compositional range, the use of sample libraries with spatially resolved analysis techniques has been proven efficient (Sakurai et al, 2007.;Deng et al, 2007;Li et al, 2008Li et al, , 2019Aono et al, 2010Aono et al, , 2011Guo et al, 2011;Sakurai et al, 2011;Wang et al, 2011;Ding et al, 2012Ding et al, , 2014Gregoire et al, 2012;Flores, 2014, 2016;Liu et al, 2016; FIGURE 1 | Pair distribution function g(r) of experimentally and ab initio calculated Co 45.5 Fe 24 Ta 6 B 24.5 .

“…Ding et al placed a gas releasing agent below combinatorial magnetron sputtered thin film metallic glasses to investigate thermoplastic formability by blow molding along the concentration gradient (Ding et al, 2014). Sheet resistivity (Li et al, 2019), resistivity (Zhang et al, 2018, Zheng et al, 2019, thermography (Aono et al, 2010(Aono et al, , 2011, laser spike annealing (Bordeenithikasem et al, 2017) and image contrast (Ding et al, 2012) have been employed to explore glass forming ability. The use of nanocalorimetry allows the determination of glass transition temperature and glass transition enthalpy (Gregoire et al, 2012).…”
