Microstructure Characterization and Properties of Graphene Oxide-Reinforced TiAl Matrix Composites
Metals, 2021 TiAl matrix composites reinforced with graphene oxide (GO) were prepared by powder metallurgy technology. The graphene oxide plates were added into TiAl powder by ultrasonic dispersion and milling, and then, shaped by Hot Isostatic Pressing (HIPing ...

Microstructure Thermal Stability and Superplastic Behavior of Al-6%Mg-0.12%Sc-0.10%Zr-0.10%(Yb, Er, Hf) Ultrafine-Grained Alloys [PDF]
arXiv, 2023 Superplastic behavior of ultrafine-grained (UFG) Al-6Mg-0.12Sc-0.10Zr-0.1X alloys, where X = Yb (Alloy #1-Yb), Er (Alloy #2-Er), and Hf (Alloy #3-Hf), has been studied. The total content of Sc, Zr, Yb, Er, Hf in the alloys was 0.32 wt.% (0.117-0.118 at.%). The alloys used for benchmarking were Al-6Mg-0.12Sc-0.20Zr (Alloy #4-Zr) and Al-6Mg-0.22Sc-0.10Zr

Short-range order in GeSn alloy [PDF]
, 2020 Group IV alloys have been long viewed as homogeneous random solid solutions since they were first perceived as Si-compatible, direct-band-gap semiconductors 30 years ago. Such a perception underlies the understanding, interpretation and prediction of alloys' properties.

XX. On the alloys of steel [PDF]
Philosophical Transactions of the Royal Society of LondonThe alloys of steel made on a small scale in the laboratory of the Royal Institution proving to be good, and the experiments having excited a very considerable degree of interest both at home and abroad, gave encouragement to attempt the work on a more extended scale, and we have now the pleasure of stating, that alloys similar to those made in the ...

Development of competitive high-entropy alloys using commodity powders [PDF]
arXiv, 2021 One of the main drawbacks of the powder metallurgy route for High-Entropy Alloys (HEAs) is the unavailability of fully pre-alloyed powders in the market. Using commodity powders (commercial Ni, Fe and Co base fully pre-alloyed powders, fully available in large quantities and at competitive prices) to produce HEAs presents a completely new and ...
