| Summary: | 75-80% dense. Biflet geometry was also a test factor, with a test material in an effort to determine some optimal billets. Maximum density achieved through compaction alone conditions for this process and its applications to powder consolidation, and there is good evidence of the possibility density in the billet, or precompacted into individual discs diameters. A solid end zone length of 3/4" produced slightly ECAE of uncompacted powder produced nearly full either uncompacted, precompacted 75-80% of theoretical Equal channel angular extrusion is a promising approach to extruded, with one half having been exposed to compaction and hardness are measured on both halves of each billet, and higher density and hardness values than those with 1/2" higher values than any other tested length. Extrusion by hole diameter being either 1/2" or 3/4", and solid end zone length varying from 1/2" to 1 1/2". billets are half metallurgy. Copper billets were filled with powder that was most part, the billets with hole diameter of 3/4" yielded obtaining full density in powder metallurgy applications. of full compaction at room samples with full or near-fuh density, 2.70 g/cm 3. For the shear, and one half undergoing compaction only. Density and temperature. these values are compared between the halves and among the This method can impose large effective deformations through uniform shear strain. Aluminum alloy 6061 powder is used as was 2.57 g/cm 3, whereas compaction and shear produced |
