Getting design ability about the appropriate conditions of the liquid state sintering with Fe and Cu powder.
2. Related theory
Sintering is usually used to form materials which have a high melting point. However, this method requires high temperature and long duration for heating in order to bond the junctions between ground material particles by congelation or diffusion. Liquid phase sintering, employed in MSL-1, makes it possible to process the sintering at lower temperature and short duration by saturating molten metals, which have lower melting points, into ground materials. At the junctions between powdered materials which have high melting points, the effect of interface force is dominant, promoting the local process of melting and eduction, and bonding between particles will be accelerated. The existence of high-density particles and the
