Powder metallurgy
Forming of the mixed powder into a compactThe dominant consolidation process involves pressing in a rigid toolset, comprising a die, punches and, possibly, mandrels or core rods. However, there are several other consolidation processes that are used in niche applications.
Sintering of the compact to enhance integrity and strengthThis process step involves heating of the material, usually in a protective atmosphere, to a temperature that is below the melting point of the major constituent. In some cases, a minor constituent can form a liquid phase at sintering temperature; such cases are described as liquid phase sintering. The mechanisms involved in solid phase and liquid phase sintering are discussed briefly in a later section.
Secondary operationsThe application of finishing processes to the sintered part. In the Powder Metallurgy industry, such processes are often referred to as secondary operations.
