In this study, an heterogeneous Ti/Al assembly is proposed for the built of aircraft structures. This kind of structure combines advantages of both materials: the aluminum is light-weight and less expensive whereas the titanium offers superior mechanical properties. A welding/brazing assembly in overlap configuration is studied. The two materials are the aluminum...$28.00

Presented at ICALEO 2013
Nowadays, spot laser welding is a full fledged part of industrial manufacturing and is routinely used due to its advantage. It generates very located temperature gradients, and therefore, induces small distortions in the pieces.
Nonetheless, many welding tests are often performed in order to choose operating parameters leading to a narrow heat affected zones and defect-free joins.
This numerical study aims to increase our understanding of the link between operating p...$28.00

Presented at ICALEO 2013
In this research, laser weldability for tailor welded blanks made of dissimilar strengths was examined. Usibor and Ductibor from ArcelorMittal were combined as high strength steel and high energy absorption steel, respectively. In the experiments, Yb:YAG laser welding were performed on butt joint specimens. After welding, the specimens were heat-treated under a high temperature condition similar to the HPF process. Mechanical and metallurgical characteristics of ...$28.00
