Abstract:
The use of microwave for sintering of green compacts during powder
metallurgy process is emerging as a novel and innovative technology
with many advantages over conventional sintering. This review paper
provides the theory of neck formation and growth that associated with
diffusion mechanisms during sintering for pure metal powder and the
dynamics of stable neck-growth summarized in the form of
mathematical equation. The effect of microwave sintering on different
pure metal powders has been mentioned to realize the potential
advantages of the microwaves sintering over conventional sintering for
better mechanical properties in the components manufactured by
powder metallurgy process.
