High-temperature wettability of aluminum nitride during liquid metal infiltration

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

The high-temperature wettability of AlN particle preforms with pure molten Cu, Al and Ph is quantified by means of drainage curves measured during pressure infiltration. By integrating the drainage curves obtained in this study, the work of immersion for e ...

Direct measurement of drainage curves in infiltration of SiC particle preforms: influence of interfacial reactivity

Andreas Mortensen, Ludger Weber, Maryam Bahraini Hasani

We present dynamic measurement of drainage curves in two systems having relevance to metal matrix composite processing, namely SiC/Al and SiC/Al-12.2at%Si. Data show that liquid/solid chemical reactions that cause a lowering of the contact angle do indeed ...

Direct measurement of drainage curves in infiltration of SiC particle preforms

Andreas Mortensen, Ludger Weber, Maryam Bahraini Hasani

Drainage curves (plots of the non-wetting fluid saturation versus applied pressure) for infiltration of SiC particle preforms with Al and Al-12.2 at.% Si are measured at 1023 K (750 degrees C) with a pressure infiltration apparatus adapted for direct track ...

Characterization of capillary forces during liquid metal infiltration

Maryam Bahraini Hasani

This thesis addresses the link between capillarity parameters, i.e. surface tension and contact angle, and the infiltration of porous preforms with molten metal by pressure infiltration The method used is to conduct pressure infiltration experiments of sel ...

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 ...
