Lightweight bimetal engine blocks, where the main body is made of an aluminum-silicon alloy
and the cylinder liner, exposed as it is to high mechanical and thermal loads, is made of grey cast iron (GCI), are a challenge to machine because the properties of the two metals differ widely.
The microstructure of nanocomposites and the interface between A356 aluminum-silicon alloy
matrix and carbon nanotubes were investigated.
In the case of aluminum-silicon alloy
, the material is heat-treated to ensure that the silicon is dispersed properly.
The pastille glue is made of silicon-bearing polymers and an aluminum-silicon alloy
The complex thin-wall extruded components of a new 6000-grade aluminum-silicon alloy
exhibit high strength and toughness and meet precision tolerance standards in both straight-length and formed configurations.
At the eutectic composition and temperature, the solidification phase transformation occurs when the liquid aluminum-silicon alloy
transforms into solid aluminum and solid silicon.
"One of our targets was to make an engine that would give diesel technology a real push." The aluminum-silicon alloy
used in Audi's production gasoline engines (its production diesels use vermicular cast iron) is used in the block and heads of the 90[degrees] V12 TDI.
Saksena, "Rare earth modifiers of aluminum-silicon alloy
," AFS International Cast Metals Journal, vol.
An aluminum matrix containing eutectic silicon comprises the microstructure of an aluminum-silicon alloy
. This silicon can appear as needle-like crystals and plates or a refined fibrous structure, depending on the level of chemical modification and the casting's cooling rate.
The block of the V8 is cast from aluminum-silicon alloy
and does not use separate cylinder liners.
Eidhed, "Fading mechanism of grain refinement of aluminum-silicon alloy
with Al-Ti-B grain refiners," Materials Science and Engineering A, vol.
Like the use of a specialist casting supplier to not only produce the aluminum-silicon alloy
block, but to completely machine it as well.
