Abstract

In the present study, an attempt was made to predict the extrusion speed and temperature during the hot extrusion of 6061 aluminium alloy chips by using Deform 3D simulation. The influence of extrusion process parameters, namely ram speed (Vr), preheat temperature (Tph), preheat time (tph) and extrusion die angle on the responses flow stress and heat distribution was investigated. One of the dies was a flat-face die, which represents a conventional extrusion die design for production of solid aluminium profiles. This study concentrated on improving the understanding of the behavior and the formation mechanism distribution with the aim of predicting the best on parameter process hot extrusion of 6061 aluminium alloy chip by using Deform 3D simulation without lubricant. Ram speed 2 mm/s at 500°C was affecting the amount of heat generated and also the amount of heat loss to the extrusion tooling and made insufficient on quality bonding. In the FEM code, the results of the simulations were compared and confirmed successfully by the experimental results.
