Sintering and Grain Growth
“powder metallurgy” that considers many of the concepts and problems that we address for ceramics One of the reasons for processing metals by sintering is to control the grain size which is precisely what we usually need to do in ceramics We can discuss the topic at different levels of complexity The phenomenon is quite straight-
Powder metallurgy P/M - University of Technology Iraq
Powder metallurgy process consists from four major steps: Production of the metallic powder Mixing and preparation of powder Pressing of powder to the required shape Heating or sintering of the compacted powder at a relatively high temperature In addition to Post Processing as shown in figure 1 & 2
Lecture 15: Powder Metallurgy - ektukz
Powder Metallurgy (PM) • Usual PM production sequence: 1 Pressing - powders are compressed into desired shape to produce green compact • Accomplished in press using punch-and-die 2 Sintering – green compacts are heated to bond the particles into a hard rigid mass • Temperatures are below melting point

What is powder metallurgy?
- POWDER METALLURGY (P/M) Feasible when the melting point of a metal is too high such as W, Ta, Mo the reaction occurs when melting such as Zr and for superhard tool materials Powder Metallurgy (PM) (around 1800s)
What are the advantages and disadvantages of powder metallurgy?
- Powder Metallurgy (PM) (around 1800s) Pressing – Powders are compressed into the desired shape in a press-type machine using punch-and-die tooling designed specifically for the part. Sintering - Heating at a temperature well below melting. Advantage Near-net shape, No waste, controlled porosity,Dimension control better than casting Disadvantage
What is the conventional method of compacting metal powders in pm?
- FIGURE 7.4: Pressing, the conventional method of compacting metal powders in PM: (1) filling the die cavity with powder, done by automatic feed in production, (2) initial, and (3) final positions of upper and lower punches during compaction, and (4) ejection of part.
Can powder metallurgy produce more complex parts with true three-dimensional geometries?
- More complex parts with true three-dimensional geometries are also feasible in powder metallurgy, by adding secondary operations such as machining to complete the shape of the pressed and sintered part, and by observing certain design guidelines PRACTICE QUESTIONS 7.1.
