2. Obtaining CMMp by powder metallurgy
2.1 General process
This is an interesting type of process, which can produce materials (alloys and/or composites) with non-equilibrium compositions and very high particle volume fractions

Obtaining CMMp from a liquid matrix
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...

Producers
There are several producers of CMMp particle-reinforced metal matrix composites in the world . Duralcan is the most important in terms of production volume, with around 11,000 t/year, and probably also in terms...
