In order to investigate the formability of metal material in semisolid state,a series of experiments were carried out by thixo-forging the complex part of aluminum alloy AlSi7Mg.Through changing the upper punch,aluminum parts with different upper-cup dimensions can be successfully produced.The numerical simulation was conducted for investigating the forming limits of AlSi7Mg during thixo-forging.It is found that the simulation result is in good agreement with the experiment one.
