Processing and micro-mechanical characterization of multi-component transition MC carbides in iron

Andreas Mortensen, Léa Deillon, Goran Zagar, Marta Fornabaio, Lionel Michelet

We prepare multi-component transition monocarbides of chosen composition by arc-melting together a pre-alloy of the transition metals and cast iron. Based on the elements Ti, Ta, V, Nb and W, 51 different binary, ternary and quaternary compositions are pro ...

Kinetic processes in the high-temperature pressure-infiltration of Al into Al2O3

Andreas Mortensen, Ludger Weber, Marta Fornabaio, Gionata Schneider

We explore the influence (i) of the interaction between aluminium and alumina, and (ii) of sodium impurities present in Bayer alumina, on the pressure infiltration of alumina particle preforms with molten aluminium. At 1000°C or above, although the alumini ...

Microscopic strength of silicon particles in an aluminium–silicon alloy

Andreas Mortensen, Martin Guillermo Mueller, Goran Zagar, 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 ...

The local strength of individual alumina particles

Andreas Mortensen, Václav Pejchal, Goran Zagar, Marta Fornabaio

We implement the C-shaped sample test method and micro-cantilever beam testing to measure the local strength of microscopic, low-aspect-ratio ceramic particles, namely high purity vapor grown a-alumina Sumicorundum (R) particles 15-30 mu m in diameter, kno ...

Silicon particle pinhole defects in aluminium–silicon alloys

Andreas Mortensen, Marta Fornabaio, Martin Guillermo Mueller

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 ...
