that liquid fraction plays an important role in the densification process which can be divided into three stages. Rolling deformation is the main densification mechanism in deformation area when... liquid phases are squeezed out and then fill into the pores, which results in the increase of relative density, as shown in Figs. 6(c) and (d). 3.2 Densification mechanism during semi-solid powder......
