AB Aluminum matrix composites (AMCs) reinforced by aluminum nitride were preparedby mechanical alloying followed by a simple press and sintering method. Milling began undervacuum and after a period of between 1 and 4 h, NH3 gas flow (1 cm3/s) was incorporated untilthe total milling time of 5 h was reached. Results show that in addition to the strain hardeningtaking place during mechanical alloying, NH3 plays an additional role in powder hardening. Thereby,the properties of the sintered compacts are strongly influenced by the amount of N incorporated intothe powders during milling and the subsequent formation of AlN during the consolidation process.The obtained AMC reaches tensile strengths as high as 459 MPa and hardness much higher than thatof the as-received aluminum compact.
