  • 발행 : 2008.10.09

초록

Due to new requirements of the automotive industry, concerning lightweight and non-corroding construction, new production methods, The Hot Air Forming process of aluminum alloys are of special interest. The disadvantage of aluminum alloy is the poorer formability compared to steel. The Hot Air Forming process is one of the forming process receiving recent attention. In the current study, Fabrication of aluminum rear subframe has been attempted using seam and seamless aluminum tubes. On the base of hot workability of the extruded tube and PAM-STAMP simulation results, Optimum condition for fabricating aluminum rear sub(lame parts by Hot Air Forming could be determined.
