Influence of Temperature and Strain Rate on the Mechanical Behaviour of Aluminium Alloy AA6060
Materials Science Forum, 2014In an attempt to improve the constitutive models for 6xxx aluminium alloys at high temperatures and high strain rates, a comprehensive test series has been carried out for AA6060. Uniaxial tension tests were performed at various strain rates from 0.01 s-1 to 1000 s-1 and temperatures from 20 °C to 350 °C.

Tensile tests on smooth and notched axisymmetric specimens were carried out to determine the large strain work-hardening curves and the ductile fracture characteristics of an AA6060 aluminium alloy for three different processing routes. The alloy was processed in three subsequent steps: 1) casting and homogenization, 2) extrusion, and 3) cold rolling ...

Conditions for Sticking Friction between Aluminium Alloy AA6060 and Tool Steel in Hot Forming
Key Engineering Materials, 2011The frictional conditions between an aluminium AA6060 alloy and tool steel in hot bulk forming have been investigated. The compressive-rotational method for frictional measurements, presented herein, represents an innovative approach for defining the thermo-mechanical conditions required for sticking friction at the interface between the two metals ...

Materials Today: Proceedings, 2015
Abstract The aim of the present paper is to study the hot deformation behavior of two different Al alloys (AA6060 and AA6063) by means of hot torsion tests in the 400-550°C temperature range, typical of real extrusion temperatures. The behavior of the alloys, in terms of equivalent stress vs.

Surface and Interface Analysis, 2019
This paper presents a short review of the literature data and the newest studies of filiform corrosion (FFC) testing of profiles extruded using a recycling‐friendly AA 6xxx aluminium alloy, with Cu content up to 0.09 wt%. As the pretreatment plays a significant role in avoiding FFC on powder‐coated aluminium profiles, the profiles were pretreated and ...

International Journal of Adhesion and Adhesives, 2017
Abstract In this study, the adhesion of a commercially applied powder coating on a steam treated AA6060 surface with pure steam and steam with citric and phosphoric acid chemistries has been investigated. Contact angle, roughness, and nanoscale pull off forces were determined as a function of the steam treatment prior to application of the powder ...

Progress in Organic Coatings, 2015
Abstract Ce-based conversion coatings (CeCCs) are a promising alternative to toxic chromate coatings on the metal substrates. In this work the CeCCs were electrodeposited on aluminium alloy AA6060 from aqueous solution of Ce(NO3)3 at different potentials (−0.95 V, −1.2 V and −1.4 V).

Electrochemical behaviour of ZrO2 sol-gel pre-treatments on AA6060 aluminium alloys
2007ZrO2 pre-treatments applied with the sol–gel technique are a possible replacement of chromium based pre-treatments on aluminium alloys. The thickness and homogeneity of the films deposited on AA6060 alloy are strongly related to the process parameters like preparation of the surface, number of dips and thermal treatment of the film.
