Xie2 (1.School of Material and Engineering, Hefei University of Technology, Hefei 230009, China;2.Institute of Tribology, Hefei University of Technology, Hefei 230009, China) Abstract:The warm powder compaction process is simulated......
Microstructure and mechanical properties of Ti6Al4V powder compacts prepared by magnetic pulse compaction LI Min(李 敏), YU Hai-ping(于海平), LI Chun-feng(李春峰) School of Materials Science...; Abstract: Ti6Al4V powder compaction was performed by using magnetic pulse compaction in air at 200......
; Abstract: Warm compaction process of pure iron powder was investigated. Due to the existence of elastic, plastic and thermal strains, a coupled mechanical and thermal model... into the constitutive integral arithmetic and solved employing incremental iterative solution strategy. The yield strength of iron powder was obtained according to the tensile experiments. When the compaction......
dimples on the whole fracture surface. Key words: warm compaction; die wall lubrication; powder metallurgy; mechanical properties _________________________________________________________ 1 Introduction... compaction is an interesting avenue to achieve high green densities at a lower cost compared to DP/DS and powder forging[4-6]. Warm compaction is the process during which mixed iron/steel powders......
