Answer / malayappan

Generally, When an aloy is to be manufacured and when the
two metals A & B do not exihibit a solubility in both
liquid and solid condition, then the most prepereble method
is Powder Metallurgy. Metal powders are mixed and with a
binding metal (having low melting point than the two
primary powders) or by mechanical bonding the components
are formed by cold or hot pressing. they are placed inside
furnace and heated to a temperature known as sintering
temperature. (generally with a third addinal bonding
metaly, to its melting point. In powder metallrgy the poder
size, sintering temperature, the compacting pressure all
play a vital role.

Answer / raghu

with the help of metallic powders we can produce small size
metal components , specially for automobile industries

Answer / a

powder metallurgy has been defined as the art and science of
producing fine metal powders and objects finished or
semi-finished shaped from individual, mixed or alloyed metal
powders with or without the inclusion of non-metallic
constituents.

Answer / sudipta panda

powder metallurgy is the process of briquetting the fine powder metal particles by mix with binders or by hot or cold pressing with the help of dies in a predetermined temperature.mostly this types processes are used in automotive industries.
