Crystal structures of hybrid precipitates have been analysed by atomic-resolution scanning transmission electron microscopy in an aged Al–Cu–Mg–Si alloy. A new unique hybrid precipitate (UHP) has been found as rod-shaped discrete particles along 100 in bulk aluminium matrix. The UHP consists of a co...

Welds made by high power laser beam have deep and narrow geometry. Addition of filler wire by the arc source, forming the laser-arc hybrid welding (LAHW) process, is very important to obtain required mechanical properties. Distribution of molten wire throughout the entire weld depth is of concern si...

The strength of a metallic alloy is controlled by the collective contribution from different strengthening mechanisms. To develop a complete numerical framework for the flow stress in alloys, it is necessary to understand the different mechanisms isolated, as well as knowing how they interact and af...

This research concerns the precipitation and subsequent dissolution of precipitate phases in an Al–0.86Mg–0.62Si–0.1Cu (at.%) alloy subjected to varying thermal exposure during an in situ heating transmission electron microscope (TEM) experiment. The distribution and crystal structure of precipitate...

Grain boundary degradation phenomena in forged CW626N alloy containing aluminium, after exposition to corrosive environment according to standard NS-EN ISO 6509-1:2014, was systematically investigated by scanning/transmission electron microscopes. Already after three minutes exposure to CuCl2 aqueou...
