Özet:

 

The densification behaviour of aluminium, iron and alumina powders  under cold isostatic pressing (CIP) are examined.  For this purpose, a  unit which can withstand up to 650 MPa pressure was designed and  constructed.  With this pressure unit, aluminium, iron and ceramic  powders, having different hardness values and different particle  sizes, were pressed and their mechanical behaviours were investigated  at pressures between 100 and 500 MPa.  Attained densities were about  100% for aluminium, 90% for iron and 65% for alumina powders.   Pressing resulted in significant increases in the microhardnesses of  iron and aluminium powders.  Light and scanning electron microscopy  examinations revealed that severe plastic deformations took place in  the powders of aluminium and iron, and no plastic deformation was  observed in alumina powders.
