The cover shows the inverse pole figure map obtained by EBSD on the cross section of an hybrid aluminium-to-steel joint produced by the Cold Metal Transfer welding technique on a specially designed butt geometry,More details can be found in the article of L. Agudo et al. on page 350. [source]

Ultrasonic Metal Welding of Aluminium Sheets to Carbon Fibre Reinforced Thermoplastic Composites (Adv. Eng.

ADVANCED ENGINEERING MATERIALS, Issue 1-2 2009
Mater.
The Cover shows a hybrid joint for multi-material lightweight components realized by ultrasonic metal welding at the Institute of Materials Science and Engineering at the University of Kaiserslautern. Ultrasonic welding is one innovative technology for joining carbon fibre reinforced polymers (CFRP) with sheet metals like aluminium alloys or aluminium plated steels. The achievable mechanical properties of the ultrasonic welded joints were carried out by using statistical test methods. One example for the evaluation of the welding results is presented on the left hand side of the Cover. Additionally a scanning electron micrograph of the bonding zone of an aluminium/CFRP-joint is shown in the background. More details about the ultrasonic welding technique can be found in the article of F. Balle, G. Wagner and D. Eifler on page 35 of this issue. [source]

Ultrasonic Metal Welding of Aluminium Sheets to Carbon Fibre Reinforced Thermoplastic Composites,

ADVANCED ENGINEERING MATERIALS, Issue 1-2 2009
Frank Balle
The ultrasonic welding technology is an innovative method to produce hybrid joints for multi-material components. The investigations described in this paper were carried out using the ultrasonic metal welding technique for joining carbon fibre reinforced thermoplastic composites (CFRP) with sheet metals like aluminium alloys or aluminium-plated steels. The achievable mechanical properties as a function of the process parameters are presented. Additionally, microscopic investigations of the bonding zone are discussed. One important advantage of ultrasonic metal welding is the possibility to realise a direct contact between the load bearing fibres of the reinforced composite and the metallic surface without destroying the carbon fibres.

Local electrochemical properties of laser beam-welded high-strength Al,Zn,Mg,Cu alloys

MATERIALS AND CORROSION/WERKSTOFFE UND KORROSION, Issue 1 2008
J. Wloka
Butt welds of two high-strength Al,Zn,Mg,Cu alloys with different zinc contents were welded by a laser beam welding technique. Due to the high energy density of the laser beam, the microstructural changes are confined to very thin regions. Electrochemical properties of the weld heat-affected zones are investigated by local electrochemical measurement techniques and correlated with microhardness measurements, macroscopic corrosion behaviour and metallographic sections. It turned out that microelectrochemical techniques, especially the EC-pen is a versatile and easy to handle tool for the resolution of changes in the electrochemical properties across a weld bead. It unveils modifications, which cannot be resolved by hardness measurements. By microcell measurements, local corrosion kinetics can be estimated. [source]
