Effects of Post-Heat Treatments on Mechanical and Electrical Properties of 6201 Aluminum Alloy

Abstract:

This study investigates the effect of introducing an intermediate solution treatment after cold drawing and before artificial aging on the mechanical and electrical properties of the 6201 aluminum alloy. The solution heat treatment was performed at 510 °C for one hour. Aging treatments were conducted at temperatures ranging from 150 °C to 200 °C for durations between 2 h and 30 h. This heat treatment route yielded comparatively softer materials, with a maximum ultimate tensile strength (UTS) of approximately 325 MPa. Electrical conductivity (EC) measurements demonstrated that the T6-temper method consistently produced higher EC values reaching values of around 63 %IACS compared to the conventional process, deomstrating inverse relationship between strength and conductivity. It was found that T6-155-30 condition produces the best combination of strength, ductility and EC of 325 MPa, 11.5% and 58.6 %IACS, respectively.
