Abstract

Rapid compression tests are useful to characterize the semisolid behaviour in thixoforming conditions The loaddisplacement curves typically display a peak load The origin the maximum value and the height of this peak are discussed comparing calculated results obtained using a micromacro model and experimental data obtained in earlier work As suggested by experiments the calculated peak load originates from a 3D continuous solid skeleton which breaks down under load For the same initial semisolid structure the model predicts that decreasing the ram speed decreases the maximum of the peak because of a strain rate effect In addition the peak load is found to be quite sensitive to initial internal structure namely the volume fraction of entrapped liquid which may change for various soaking times Finally the time for the solid skeleton breakdown is found to be in good agreement with experimental results
