The sintering Purpose-to increase strength & hardness of a green compact Carried out at a temperature below the highest melting constituent. Furnaces may be either the electric resistance,gasfired or oil fired type. Principal variables-temperature(generally within 70-90% of the melting point of metal or alloy),time(10min.-8 hours)&furnace atmosphere. Sintering process is concerned with -diffusion(surface of particles as temperature rises) -densification(decreases porosity,increase particle …
