Abstract

Effects of the extrusion ratio, on-line solution temperature and cooling speed on the microstructures, mechanical properties and conductivity of AA-6201 feedstock have been investigated. Experimental results show that the size of the grain of the feedstock grows slowly with an increase of on-line solution temperature, the size of strengthening phase becomes smaller and the density becomes bigger with an increase of extrusion ratio. The tensile strength of AA-6201 feedstock after T-6 treated increases with an increase of extrusion ratio, on-line cooling speed, and with a decrease of solution temperature, and the conductivity is a little penalty. Under the conditions of the extrusion ratio 16.5, on-line solution temperature 793.15K and ageing temperature 423.15K, the tensile strength, elongation and conductivity are 324 MPa, 10.1 % and 53.0% IACS respectively. A feedstock with high quality can be produced by a method of continuous casting and extrusion.
