Trans. Nonferrous Met. Soc. China 26(2016) 2162-2169 Deformation and densification behavior of discrete media filled thin-walled tubes during forward extrusion Tong WEN1, Qing LIU1, Qian HUANG1, Wen... in compaction and densification of it. Loose powders filling leads to higher extrusion load. Due to dissimilar migration behaviors of the particles, the load-stroke curves of the tubes filled with fine......
