Powder-metallurgy fabrication of ZrB2-hardened Zr3Al2intermetallic composites by high-energy ball-milling and reactive spark-plasma sintering
(Elsevier, 2022)
A powder metallurgy route combining high-energy ball-milling (HEBM) of elemental powders and reactive spark-plasma sintering (SPS) is proposed for the controlled fabrication of novel composites based on a Zr-Al intermetallic ...

Scratch, Fretting, and Sliding Wear of a ZrB2–hardened Zr3Al2 Intermetallic–ceramic Composite
(Elsevier, 2023)
The unlubricated wear behaviour of a very recently developed ZrB2–hardened Zr3Al2 intermetallic–ceramic composite was investigated for the first time. In particular, tribological tests of scratch, fretting, and sliding ...

Reactive SPS for sol–gel alumina samples: Structure, sintering behavior, and mechanical properties
(Elsevier, 2021)
This work presents a fast and direct controlled routine for the fabrication of fully dense alumina based on the reactive spark plasma sintering (reactive-SPS) of boehmite (γ-AlOOH) nano-powders obtained by the sol–gel ...

Quantifying structural disorder in spinels by X-ray diffractometry through constrained–restrained Rietveld refinements
(Elsevier, 2023-06)
Accurate determination of the structural disorder (i.e., cation misplacement, anionic and cationic vacancies, and reduced cations) of spinels is crucial to understanding the properties of this technologically attractive ...

Processing of ZrB2 tribo-ceramics by reactive spark plasma sintering of ZrH2+2B subjected to high-energy pre-ball-milling
(Elsevier, 2023-09)
The reactive spark plasma sintering (RSPS) of monolithic ZrB2 ceramics from ZrH2+2B powder mixtures subjected to shaker pre-milling was investigated, and compared with other three sintering approaches. It was found that ...

Parallel Cellular Automata-based Simulation of Laser Dynamics using Dynamic Load Balancing
(InderScience Publishers, 2008)
We present an analysis of the feasibility of executing a parallel bioinspired model of laser dynamics, based on cellular automata (CA), on the usual target platform of this kind of applications: a heterogeneous non-dedicated ...
