In this paper we investigate the mechanism of strengthening in Si reinforced Ti6244 alloys. As the beneficial or detrimental effect of silicide precipitation is still debated, we bring some deeper understanding of the effect of Si in near- titanium alloys. In order to provide some insights, extensive characterizations have been carried out at two ...

This study developed a non-equiatomic Ti28.33Zr28.33Hf28.33Nb6.74Ta6.74Mo1.55 super-solid solutionized BioHEA using laser powder bed fusion (LPBF) to reach the full potential as BioHEA. We succeeded in significant suppression of elemental segregation, thus, resulting in a single crystalline-like texture by activating layer-to-layer epitaxial growth...

In the present work the microstructural evolution, tensile properties, and deformation behavior of additively manufactured equiatomic CoCrFeMnNi high entropy alloy (HEA) were investigated at a cryogenic temperature (77 K). Metal additive manufacturing components are known to have exceptional yield strength, without compromising ductility. Here, las...
Vanadium-based alloys are considered to be one of the most promising hydrogen storage materials due to their high hydrogen storage capacity under ambient conditions. However, their complex activation at high temperature and poor stability pose serious challenges for large-scale applications. In this work, a series of TiCr3V16Cex (x = 0, 0.1, 0.2, 0...

Transparent Ce:lutetium aluminum garnet (Ce: Lu3Al5O12, Ce:LuAG) ceramics have been regarded as potential scintillator materials due to their relatively high density and atomic number (Z(eff)). However, the current Ce:LuAG ceramics exhibit a light yield much lower than the expected theoretical value due to the inevitable presence of Lu-Al antisite ...

© 2022 Acta Materialia Inc.Materials manufactured through conventional powder metallurgy (PM) techniques generally exhibit inferior tensile properties due to structural defects. Nevertheless, a recently proposed cold-consolidation technique using powder high-pressure torsion represents well-manufactured structures with ultra-high tensile properties...
