The electrical conductivity of microcellular metals

Andreas Mortensen, Ludger Weber

The electrical conductivity of metallic foams varies strongly with porosity. Data are presented for replicated open-pore microcellular metal over a wide range of relative density. These data, together with data from the literature for different foam struct ...

Damage accumulation during cyclic loading of a continuous alumina fibre reinforced aluminium composite

Andreas Mortensen, Ludger Weber, Benedikt Moser

Fibres fracture gradually during the fatigue cycling of continuous alumina fibre reinforced aluminium. The number of fibre breaks increases linearly with the logarithmic cycle number, depends on the maximum stress and the stress ratio, and agrees with publ ...

Longitudinal deformation of fibre reinforced metals: Influence of fibre distribution on stiffness and flow stress

Andreas Mortensen, Benedikt Moser, Andreas Rossoll

A computational analysis of the longitudinal deformation of continuous fibre reinforced metals is presented. Elastic and elastic-plastic matrix behaviour are considered. Analytical approaches are confronted with finite element analyses (FEA) for varying fi ...

Measuring and tailoring capillary forces during liquid metal infiltration

Andreas Mortensen, Ludger Weber, Maryam Bahraini Hasani, Masahiro Kida

A new technique is proposed for the direct measurement of capillary forces in systems of relevance to the infiltration processing of metal matrix composites. Capable of handling melt temperatures up to 1500 K and infiltration pressures up to 20 MPa, the te ...

Wetting in infiltration of alumina particle preforms with molten copper

Andreas Mortensen, Ludger Weber, Maryam Bahraini Hasani

The high-temperature wettability of alumina particulate preforms by copper is investigated by means of infiltration experiments conducted at 1473 K under low oxygen partial pressure. Wetting is quantified in terms of drainage curves, which plot the volume ...

Damage evolution in Saffil alumina short-fibre reinforced aluminium during tensile testing

Andreas Mortensen, Ludger Weber, Reza Tavangar Hamzehkolaei

The evolution of microstructural damage during tensile deformation of pure aluminium reinforced with 10 vol.% alumina short fibres is studied by monitoring the evolution of density and Young's modulus as a function of tensile strain. It is found that Young ...

Ductility of Saffil(TM) short fibre reinforced metals

Andreas Mortensen, Ludger Weber, Reza Tavangar Hamzehkolaei

It is proposed that a critical combination of matrix strain hardening exponent and fibre volume fraction must be exceeded to confer attractive tensile ductility to short-fibre reinforced metal. © 2005 Acta Materialia Inc. Published by Elsevier Ltd. Al ...
