DISCONTINUOUSLY-REINFORCED METALS (DRX)

What is DRX?

DRX= Discontinuously Reinforced Metals (X) X=Al, Ti, Mg etc.

Reinforcement is typically SiC or Al2O3, particles or whiskers

How is it made?

Powder Metallurgy (P/M), Stir Casting, Squeeze Casting

Characteristics of DRX

• moderate cost
• good specific s, E
• good wear resistance
• moderate CTE
• isotropic properties
• conventional processing
• supportable technology
