316 l stainless steel powder alloy powder
system, the original system of alloy powder is a kind of uniform system of a
single group, in this system is composed of uniform, but there are constituent
fluctuations, or some group yuan exists partial poly (microscopic level) to
form a high energy region, especially in the grain boundary and interdendritic,
when reaching a certain temperature (above the solidus temperature), these
areas are preferred melt flowing liquid phase in the grain boundary extension
formation, make the particles into grain, grain activity is bigger, easy to
implement rearrangement movement, get a higher degree of densification.
