Abstract:Warm compaction behaviors and their affecting factors such as compaction temperature, compaction pressure and lubricant concentration were studied. Effect of die wall lubrication on the powder’s warm compaction behavior was also studied. The use of smaller size colloidal graphite investigated ca, n give a higher compact density and lesser spring-back effect than the use of flake graphite.
Key words: warm compaction behavior； iron-based powder metallurgy； spring-back effect
