Pore-free composites combining alumina particles within a matrix of pure aluminium are produced by pressure infiltration, varying systematically the degree of the contiguity, beta, of the ceramic phase by sintering prior to infiltration. The thermal expans ...
In the current research, pressureless melt infiltration (PM!) was applied to study the effect of different processing conditions on the final properties of Al/SiC composites, fabricated through the infiltration of aluminum melt into SiC particulates porous ...
Aluminum nitride (AlN) has been applied to various applications, including electronic substrates and packaging, semiconductor production components, wide band gap semiconductor, light-emitting diodes (LED) and acoustic wave devices; at the same time, it is ...
The role of reinforcing phase contiguity in high volume fraction particulate composites is investigated using model composites of pure aluminium reinforced with α-Al2O3 particles. To produce the composites, alumina particle (5µm) preforms were either loose ...
The mechanical response of the reinforced active alloy Incusil (TM) ABA (R)-SiC is studied. Specimens with up to 27 vol.% SiC particles are produced and tested in tension. The presence of the reinforcement leads to modifications in the alloy mechanical res ...
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 ...
The threshold pressure P-0 for infiltration of Al-12 wt.% Si alloy into compacts of mixtures of alumina and silicon carbide particles having largely different size is investigated. The results are in line with those recently derived from infiltrations of A ...
Tungsten-iron alloy was produced by electrodeposition. The electrodeposited alloy (15 at.% W) possesses a two-phase composite microstructure, containing a nanocrystalline phase of distorted BCC structure with a grain size between 50 to 150 nm and an amorph ...
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 ...
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 ...
