Purpose The aim of this study was to develop a die forging process for producing aircraft components made of magnesium alloy AZ61A using a screw press. Design/methodology/approach The proposed forging technique was developed based on the results of numerical and experimental research. The required forging temperature was determined by upsetting cylindrical specimens on a screw press in order to examine both plasticity of the alloy and quality of its microstructure. The next stage involved performing numerical simulations of the designed forging processes for producing forgings of a door handle and a bracket, both made of magnesium alloy AZ61A. The numerical modelling was performed using the finite element method-based on simulation programme, Deform 3D. The numerical results revealed that the forgings are free from material overheating and shape defects. In addition to this, the results also helped determine the regions which are most prone to cracking. The final stage of the research involved performing ...
