Backward Extrusion Process Analysis and Ductile Fracture Minimization of Titanium

티타늄합금의 후방압출 공정해석 및 연성파괴 최소화

Titanium alloys are a vital element for developing advanced structural components, especially in aerospace applications. However, process design for successful forming of titanium alloy is a difficult task, which is to be achieved within a very narrow range of process parameters. Presented in this paper is a finite element - based optimal design technique as applied to ductile fracture minimization process design in backward extrusion of titanium alloys.
