Özet:

 

In this study, Al powders containing 3% wt carbon black were  mechanically alloyed in a high energy ball mill for 20 h.   Mechanically alloyed powders were compacted at various pressures (400,  500, 600, and 700 MPa) to produce specimens with dimensions of 6.35 x  12.70 x 31.70 mm.  Specimens were then sintered at 500, 600, 650, and  700°C for 5 h under argon atmosphere in a tube furnace.  XRD analysis  was carried out to see the Al4C3 transformation.  SEM  analysis was conducted to determine the sintering behavior of the  powders.  Transverse repute strength and hardness tests were carried  out to fined the mechanical properties of specimens.  The results  showed that ideal compacting pressure was 600 MPa and the ideal  sintering temperature was 650°C for good mechanical properties.
