Abstract
Numerical simulation and experiment were employed to analyse the compression of square ring of 7075 aluminium alloy. The effect of deformation condition on metal flow behaviour was analysed during square ring compression. The results indicate that deformation uniformity increases obviously as height-diameter ratio increases and the metal flow outwards along radial direction increases for the same. Consequently, the complex degree of metal flow behaviour is enhanced. Through experiment verification, the results coincide well with the simulated results, which provides theoretical references for the investigation of pre-fabricated billet technology.

Key words
