CDA 365/Al 1100과 Al 2014/Al 1100 이중 관의 다소재 압출에 관한 연구
A Study on the Multi-Billet Extrusion of the Two-Layer Tubes by CDA 365/Al 1100 and Al 2014/Al 1100
초록
A new forming method for metal/ other metal two-layer tubes by multi-billet extrusion (MBE) is introduced. The forming possibilities of two-layer tubes CDA 365(inner)/Al 1100(outer) and Al 2014(inner)/Al 1100(outer) by MBE are investigated according to the given frictional condition and die profile. The results show that two-layer tube composed by two types tube as abovementioned can be manufactured by MBE. Some stated variables in the forming process such as effective stress and normalized pressure at welding surface are analyzed by FEM code (
