The preparation and processing of powdered iron and
non-ferrous metals is called Powder Technology.Parts made by
this process cannot be produced in any other way.
Powdered metal is filled in the die and heated to just
below melting temperature and then the powder metal is
compacted under high pressure to give the required
shape.The process of heating the powder metal in the die is
called sintering.

Answer / rakesh swami

Powder technology is a method of manufacturing in which metal power is used to get the final shape of the object.The general procedure is as follows-
1. Manufacturing of powder (Atomization, Reduction, Grinding, Electrolytic deposition, milling of brittle materials, commutition etc)
2. Blending with lubricants (Graphite) and binders (methylcellulose, thermoplastics etc)
3. Compaction (compressed b/w dies)
4. Sintering (heated at almost 0.75*Tmelt)
5. Secondary machining and finishing if necessary
6. Secondary heat treatment if necessary
7. Oil impregnation, PVD, CVD etc as per requirement
