“…LAM can produce compositionally graded materials, making it a powerful tool for rapid combinatorial material exploration [160] . DED is the more common method used to produce graded materials, as the multiple nozzles can be coaxially aligned with the laser, ensuring that each nozzle's flow rate can be individually adjusted to spatially control the deposited alloy composition [162,163] . By dynamically changing the flow rate during AM, a compositional gradient can be formed, allowing for the exploration of a large compositional space within the same sample [164,165] .…”

High-entropy alloys (HEAs) are an emerging class of alloys with multi-principal elements that greatly expands the compositional space for advanced alloy design. Besides chemistry, processing history can also affect the phase and microstructure formation in HEAs. The number of possible alloy compositions and processing paths gives rise to enormous material design space, which makes it challenging to explore by traditional trial-and-error approaches. This review highlights the progress in combinatorial high-throughput studies towards rapid prediction, manufacturing, and characterization of promising HEA compositions. This review begins with an introduction to HEAs and their unique properties. Then, this review describes high-throughput computational methods such as machine learning that can predict desired alloy compositions from hundreds or even thousands of candidates. The next section of this review presents advances in combinatorial synthesis of material libraries by additive manufacturing for efficient development of high-performance HEAs at bulk scale. The final section of this review discusses the high-throughput characterization techniques that are used to accelerate the material property measurements for systematic understanding of the composition-processing-structure-property relationships in combinatorial HEA libraries.

“…Detailed studies have been reported in the literature on the use of DED for the fabrication of multi-material structures. Research studies showed that laser engineered techniques can be used to produce metallic multi-material parts with high strength and good surface quality [91][92][93]. The main advantage of the DED process is the availability of a wide range of materials, and material interfaces can be produced with high strength.…”

Additive manufacturing has already been established as a highly versatile manufacturing technique with demonstrated potential to completely transform conventional manufacturing in the future. The objective of this paper is to review the latest progress and challenges associated with the fabrication of multi-material parts using additive manufacturing technologies. Various manufacturing processes and materials used to produce functional components were investigated and summarized. The latest applications of multi-material additive manufacturing (MMAM) in the automotive, aerospace, biomedical and dentistry fields were demonstrated. An investigation on the current challenges was also carried out to predict the future direction of MMAM processes. It was concluded that further research and development is needed in the design of multi-material interfaces, manufacturing processes and the material compatibility of MMAM parts.

“…"Thin FGMs" are manufactured by different methods like physical vapor deposition (PVD) [109], chemical vapor deposition (CVD) [130,131], thermal spray deposition [132] and self-propagating high temperature synthesis (SHS) techniques like laser cladding ( Fig. 8) [133][134][135], while "Bulk FGMs" are manufactured by powder metallurgy [136,137], centrifugal casting [138,139], solid freeform techniques [140], gravity settling. Thin FGMs ranges between 5 nm and 500 nm [141,142] and may be extended to the micro-meter range (e.g.…”

Functionally graded materials classifications and development trends from industrial point of view

Over the last few years, many classifications have been proposed for functionally graded materials (FGMs). In this Paper, critical review of different available classifications for FGM based on their physical, structural and manufacturing characteristics are presented. Advantages and limitations of each fabrication method for use in a given application is correspondingly considered. In addition, new classifications based on gradation control and accuracy, residual stresses, specific energy consumption, environmental impact evaluated throughout the complete life cycle and manufacturing costs are proposed. These classifications mainly reflect the needs of both FGM designers and industrial manufacturers. Based upon the presented classifications and the recent advances in analysis and production techniques, new major directions for FGMs research are proposed.
