Abstract Scope |
Billet form solid aluminum into extrusion die in pieces with force of the ram and then welding of aluminum to form hollow profile as solid diffusion process. In this study, the effects of the addition of bismuth element, which is found in liquid form during the aluminum extrusion temperature to 6082 aluminum alloy, which is highly used in railway industry on billet microstructure and mechanical properties of the alloy, were investigated. 355 mm / 14 inches diameter 6082 aluminum alloy billets bismuth included produced with direct chill casting method. Casting speed and cooling water flowrate parameters were studied in casting operation. After casting, in order to stabilize the billet microstructure, homogenization thermal treatment done at 530 ° C for 6 hours. Microstructure of the billet was characterized with an optical microscope, SEM and EDS. Tensile test specimen produced from billet samples and mechanical properties determined according to 6892-1. |
