3. Obtaining CMMp from a liquid matrix
3.1 General
Foundry processes have received the most industrial development, probably because of the small number of parameters to be controlled during production, and above all because of the use of well-known, inexpensive foundry processes, well suited to high production volumes.
The general principle is simple: the liquid metal is vigorously stirred while the particles are introduced, thereby increasing particle wetting. After stirring,...

Costs
Today, the cost of reinforcing particles is highly variable, with a downward trend in prices. For example, a pound (= 0.454 kg) of particles can vary from 2 to 40 Canadian dollars, depending on the nature and size of the particles, whereas a pound of processed aluminum (finished parts) used to cost only 1 to 2 dollars, depending on the alloy and, above all, the quantity. We need to keep a close eye on the price of aluminum, which...
