In-situ strength of individual silicon particles within an aluminium casting alloy

Andreas Mortensen, Goran Zagar, Martin Guillermo Mueller

Measurements of local strength are performed in-situ on individual silicon particles that constitute the second phase of aluminium alloy A356. Particles are shaped using Focused Ion Beam (FIB) milling such that, upon the application of a compressive force ...

The Gaia-ESO Survey: properties of newly discovered Li-rich giants

Carmela Lardo, Joao André Gomes de Sá e Sousa, Fadi Atef Bayoud

Aims. We report 20 new lithium-rich giants discovered within the Gaia-ESO Survey, including the first Li-rich giant with an evolutionary stage confirmed by CoRoT (Convection, Rotation and planetary Transits) data. We present a detailed overview of the prop ...

Strength and fracture of silicon second-phase particles in aluminium casting alloys

Martin Guillermo Mueller

The mechanical behaviour of metallic materials that have a microstructure composed of a brittle phase embedded in a ductile matrix is dictated by a complex interplay of factors such as local phase properties, cohesive properties, geometrical characteristic ...

Silicon particle pinhole defects in aluminium–silicon alloys

Andreas Mortensen, Martin Guillermo Mueller, Marta Fornabaio

It was recently shown that silicon particles in heat-treated Al–Si casting alloys can contain flaws such as surface pinholes and grooves, which cause varying degrees of reduction in the in situ particle fracture strength and hence influence the mechanical ...

Characterization of Surface State of Inert Particles: Case of Si and SiC

Hubert Girault, Fernando Cortes Salazar, Véronique Amstutz, Desire Martial Koutouan Abro

Silicon and Silicon carbide particles have been investigated by the mean of infrared (IR) spectroscopy and X-ray photoelectron spectroscopy (XPS) to establish their surface states. The results of this research are based on the estimation of the area under ...

Microscopic strength of silicon particles in an aluminium–silicon alloy

Andreas Mortensen, Goran Zagar, Martin Guillermo Mueller, Marta Fornabaio

A microscopic three-point bending test that measures the strength of faceted particles of high aspect ratio is developed and used to probe individual coarsened plate-like silicon particles extracted from the eutectic Al-12.6%Si alloy. Focused ion beam mill ...

Fabrication and characterization of wafer-level deep TSV arrays

Michail Zervas, Yusuf Leblebici, Yüksel Temiz

Three Dimensional (3D) integration, based on through silicon vias (TSV), has the potential to become a key enabling technology for many applications. TSVs are commonly categorized according to their aspect ratio and diameter. An equally important parameter ...

Resistive Programmable Through Silicon Vias for Reconfigurable 3D Fabrics

Giovanni De Micheli, Davide Sacchetto, Michail Zervas, Yusuf Leblebici, Yüksel Temiz

In this letter we report on the fabrication and characterization of titanium dioxide (TiO2)-based resistive RAM (ReRAM) co-integration with 380 ìm-height Cu Through Silicon Via (TSV) arrays for programmable 3D interconnects. Nonvolatile resistive switching ...

The temporal dynamics of feature integration for color and form

Michael Herzog

When two visual stimuli are presented in rapid succession only one fused image is perceived. For example, a red disk followed by a green disk is perceived as a single yellow disk (e.g., Efron, Perc Psychophys, 1973). For two verniers that last 30ms each, i ...
