4. Working principle
During the compression process of external force, as the powder moves and deforms, the gaps are filled, the contact area between particles increases, the atoms are attracted and the mechanical wedging between particles is strengthened, thus forming a compact with density and strength. During the process of forming the compact, the changes in resistance, resistivity and conductivity are measured in real time until they are stable.
