Direct selective laser sintering of aluminium alloy powders [PDF]

open access: yes, 2008
The SLS/SLM of aluminium powder had been investigated by studying the effect of powder properties and laser processing parameters on the microstructures and properties of both single layer and multiple layer builds. On the basis of experimental evidence,

Densification and preservation of ceramic nanocrystalline character by spark plasma sintering [PDF]

open access: yes, 2012
Spark plasma sintering is a hot pressing technique where rapid heating by dc electric pulses is used simultaneously with applied pressure. Thus, spark plasma sintering is highly suitable for rapid densification of ceramic nanoparticles and preservation ...

Discrete element method sintering simulation

open access: yes, 2022
S.97-114The sintering models described in previous chapters consider only a limited number of particles or analytical analyses of sintering, without a close connection to the sintering of large parts.

Effect of 1 wt% LiF additive on the densification of nanocrystalline Y2O3 ceramics by spark plasma sintering [PDF]

open access: yes, 2011
Densification of nanocrystalline cubic yttria (nc-Y2O3) powder, with 18 nm crystal size and 1 wt% LiF as a sintering additive was investigated. Specimens were fabricated by spark plasma sintering at 100 MPa, within the temperature range of 700–1500 °C ...

The effect of precursor composition and sintering additives on the formation of ß-sialon from Al, Si and Al2O3 powders [PDF]

open access: yes, 2011
A study was performed to investigate the effect of increasing the Al or Al2O3 precursor content, above the stoichiometric amount, on the formation of β-sialon by pressureless sintering of Al, Si and Al2O3 powders in flowing nitrogen gas.

Sintering Kinetics of Plasma-Sprayed Zirconia TBCs

open access: yes, 2007
A model of the sintering exhibited by EB-PVD TBCs, based on principles of free energy minimization, was recently published by Hutchinson et al. In the current paper, this approach is applied to sintering of plasma-sprayed TBCs and comparisons are made ...

Mechanisms Involved in the Formation of Secondary Structures on the Friction Surface of Experimental Aluminum Alloys for Monometallic Journal Bearings

open access: yesLubricants, 2018
The processes taking place on the friction surface of high-alloyed aluminum alloys working with steel whilst replacing bronze journal bearings with aluminum are investigated. In this regard, eight experimental aluminum alloys with an Sn content from 5.4%
