| Abstract: |
| As an important technological method of powder metallurgy ,the normal compacting techniques have been replaced by cold isostatic pressing which is provided with outstanding superiority. this thesis is aimed at those cracks of base that is formed by metal powder which was compacted by cold isostatic pressing on certain conditions ,from every step of the whole compacting process for cold isostatic pressing to metal powder which include: the features of powder, materials of mould, filling and compaction, pressure maintaining, pressure release, demoulding and so on, analysing each possible cause of cracks that have emerged and corresponding effective resolutions. |
