Powder metallurgy (PM) is a term covering a wide selection of methods in which materials or components are made from metal powders. PM procedures can steer clear of, or drastically decrease, the want to use metallic elimination processes, thus drastically lowering generate losses in manufacture and often ensuing in decrease expenses.

The powder metallurgy push and sinter process generally is made up of a few fundamental steps: powder blending (pulverisation), die compaction, and sintering. Compaction is typically done at area temperature, and the elevated-temperature procedure of sintering is generally executed at atmospheric stress and under cautiously controlled ambiance composition. Optional secondary processing these kinds of as coining or heat treatment often follows to acquire particular properties or enhanced precision.

Mixing of powders
This can frequently involve the introduction of alloying additions in elemental powder kind or the incorporation of a urgent lubricant.

Forming of the combined powder into a compact
The dominant consolidation approach requires pressing in a rigid toolset, comprising a die, punches and, perhaps, mandrels or main rods. However, there are several other consolidation processes that are utilized in niche apps.

Sintering of the compact to enhance integrity and toughness
This approach phase requires heating of the materials, usually in a protecting atmosphere, to a temperature that is beneath the melting stage of the main constituent. In some cases, a small constituent can form a liquid stage at sintering temperature such circumstances are described as liquid section sintering. The mechanisms involved in solid section and liquid phase sintering are discussed briefly in a later part.

Secondary operations
The software of ending procedures to the sintered element. In the Powder Metallurgy industry, such procedures are frequently referred to as secondary functions.
