Fabrication of Ti-6Al-4V alloy powder by a novel sintering-deoxygenation process
Given the high cost of fabricating the Ti-6Al-4V alloy powder by the traditional hydriding-dehydriding and atomization methods, a novel sintering-deoxygenation process was proposed and studied in this research. With the help of the developed deoxygenation treatment, value-added raw materials such as Ti sponge can be substituted by low-cost and low-...

Synergy of tensile strength-ductility in IN718/CoCrFeMnNi/IN718 multi-material processed by powder high-pressure torsion...
© 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...
Printability enhancement and mechanical property improvement via in situ synthesis of carbon nanotubes on aluminium powd...
A strategy of powder surface functional modification involving in situ synthesis of carbon nanotubes (CNTs) on Al powder is described to address the poor forming ability and inferior mechanical properties of Al parts produced by laser powder bed fusion. The obtained CNTs-Al composite powder exhibited a combination of high sphericity and flowability...

Enhancement of tensile strength in AA 6061-T6 plates joined by gas tungsten arc welding using high entropy alloy filler ...
This work has focused on enhancing the tensile strength of AA 6061-T6 plates by gas tungsten arc welding (GTAW) using an AA 1100-O sheet embedded with a high entropy alloy (HEA, Cr0.14Fe0.13Al0.26Cu0.11-Si0.25Zn0.11) as a filler metal. HEA filler sheets were prepared by accumulative roll bonding (ARB). The prepared (AA 1100-O)-HEA filler metal was ...
In Situ Growth of Carbon Nanotubes on Ti Powder for Strengthening of Ti Matrix Composite via Nanotube-Particle Dual Morp...
In situsynthesis of carbon nanotubes (CNTs) on Ti powder decorated with Ni catalyst enabled us to obtain a high-quality CNTs/Ti composite powderviafluidized bed chemical vapor deposition (FBCVD) process. The composite powder was characterized by a combination of high structural integrity and uniform dispersion of CNTs, which is not obtained by trad...
