| Abstract: | Powder metallurgy components are manufactured by compacting metal powders. Hence, compaction pressure affects the properties of the components. In the present case, pre-alloyed cartridge brass (70:30) powder is employed for investigation and the effect of compaction pressure on dimensional properties of components is studied. A volumetric shrinkage is observed at various levels of compaction pressure. The shrinkage reduces with an increase in compaction pressure. It is 1.0% at 242 MPa, which reduces further to 0.4% at 725 MPa. At high level of compaction pressure, the shrinkage is found along the diameter. A swelling of 1.0% in diameter is exhibited at low level. |
