Microstructural refinement and anomalous eutectic structure induced by containerless solidification for high-entropy Fe–Co–Ni–Si–B alloys

Intermetallics (Barking), 2020
The mechanical properties of high-entropy alloys (HEAs) strongly depend on their microstructural features. In this work, the phase formation and morphologies of Fe26.7Co26.7Ni26.7Si8.9B11.0 HEAs fabricated under different undercooling levels by the drop ...

Modeling remelting induced destabilization of lamellar eutectic structure in an undercooled Ni-18.7 at.% Sn eutectic alloy

Journal of Alloys and Compounds, 2020
Achieving a high melt undercooling (ΔT) is expected as an effective strategy to significantly reduce lamellar spacing of bulk eutectic alloys. However, the undercooled eutectic alloys usually exhibit coarse anomalous eutectic structure (AES) when ΔT ...

Effect of water on the structure and dynamics of choline chloride/glycerol eutectic systems

Journal of Molecular Liquids, 2021
Deep Eutectic Systems (DESs) are an emerging class of green solvents with a myriad of applications, from biotechnology to material science. The high viscosity of most DESs is an obstacle that can be circumvented by the addition of water.

In situ observation of remelting induced anomalous eutectic structure formation in an undercooled Ni-18.7 at.% Sn eutectic alloy

, 2020
The forming mechanism of anomalous eutectic structure (AES) in undercooled eutectic alloys has been a controversial issue. In this work, we conducted in situ observation of the AES forming process in an Ni-18.7 at.% Sn eutectic alloy using a high ...

Pretreatment of sugarcane bagasse with deep eutectic solvents affect the structure and morphology of lignin

Industrial crops and products (Print), 2021
Elucidating the structural characteristics and changes of lignin during biorefining is considerably significant for lignin valorization. Deep eutectic solvent (DES), as a green solvent, has shown excellent performance in extracting high-purity lignin ...

A new infinite solid solution strategy to design eutectic high entropy alloys with B2 and BCC structure

Scripta Materialia, 2021
Eutectic highentropy alloys (EHEAs) have attracted wide attention in the metallic materials community because of its excellent castability, fine and controllable microstructure. However, the design method for eutectic EHEAs is still a challenge.

The characterization of eutectic structures

Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1973
Abstract Many attempts have been made in the past to bring order to the near-bewildering array of eutectic morphologies. These have met with limited success due mainly to the fact that the morphology of a particular eutectic may be highly dependent on both chemical composition and the rate of freezing.

The Structure and Properties of LiPb Eutectic and Near-Eutectic Alloys

Fusion Science and Technology, 2009
Li17-Pb83 eutectic is considered as one of the option for ITER test blanket and breeder blanket of DEMO reactor. Properties of Li-Pb eutectic define the conditions of its application and breeder blanket design and vice versa - operating conditions affect to the properties of eutectic that resulted in structure and properties changes.
