| Abstract |
Thermo-viscoplastic responses and densification behaviors of porous alloy steel preforms under hot upsetting are investigated. By using the relationship between Rockwell hardness and relative density for sintered porous alloy steel, density distributions of upsetted specimen are investigated. |
