Predicting the Warm Forming Behavior of WE43 and AA5086 Alloys [PDF]
Procedia Engineering, 2017 In the present work, we have studied the formability behaviour of two types of magnesium alloys, WE43 hot rolled and WE43 cold rolled by carrying out uniaxial tensile test at elevated temperatures of 350 °C to 500 °C both experimentally and numerically at a constant strain rate of 10-3s-1.

Warm Hydroforming Process under Non-Uniform Temperature Field for Magnesium Alloy Tubes
Metals, 2021 The warm tube hydroforming (WTHF) process of lightweight materials such as magnesium alloy contributes to a remarkable weight reduction. The success of the WTHF process strongly depends on the loading path with internal pressure and axial feeding and ...
