Study on y-shape tube hydroforming of magnesium alloys at elevated temperatures
Source abstract
Abstract
In this paper, uniaxial tensile tests are firstly conducted to evaluate the flow stress of AZ61 magnesium alloy at different temperatures and strain rates. A commercial finite element code of DEFORM 3D is used to simulate the plastic deformation of AZ61 magnesium alloy tube during a y-shape hydroforming process at elevated temperatures. The effects of loading paths with different feeding speed ratios and initial tube positions on the contact area at the counter punch surface at the bulge stage are discussed. The effects of friction coefficient on the contact area at the counter punch surface are also investigated. Finally, using a testing machine with a capacity of 40 tons of axial feeding, 30 MPa of internal pressure and 300oC of maximum temperature, y-shape hydraulic forming experiments of AZ61 magnesium alloy tubes at elevated temperatures are carried out. The analytical flow line patterns and thickness distribution of the formed product are compared with the experimental results.
