The annual report from the Department of Materials initiate a second international program in 2008. 33 master Science and Engineering (DMSE) consists of two parts. The students graduated from DMSE in 2007, and the number first part comprises short reports giving an impression is expected to increase in the years ahead. The number of of the current research conducted in the four research exchange students from European universities at NTNU is groups at DMSE, the annual list of publications and also increasing. This year the number of exchange students conference proceedings and the laboratory infrastructure at DMSE was 37. The first students were also enrolled in at DMSE. We hope that this first part of the annual report the new program in nanotechnology at NTNU in 2006, and give external readers an impression of the research being DMSE has ambitions to be one of the leading departments performed at DMSE.

Physical metallurgy Dendrite fragmentation in aluminium alloys
Columnar-to-equiaxed transition has been studied in situ by X-radiography.
Fragmentation of columnar dendrites during growth is important for the formation of an equiaxed zone in castings. This phenomenon has been studied in situ by X-radiography during directional solidification of Al- Cu alloys. The observations demonstrate that different mechanisms promote dendrite detachment at different location on the mush and compare well with models proposed for fragmentat ion.
Buoyant and settling motions of crystals and liquid play an important role for the detachment of crystal fragments, for their transport out of the columnar mush and for their possibility of survival in the melt and promote a columnar- to-equiaxed transition in the casting. Fragmentation close to the dendrite growth front in the sequence shown below is due to heavy Cu-rich melt that flows into the mush and

The metal is induction melted in a quartz crucible and is extruded through an orifice by applying a top pressure of inert gas. When the melt hits a spinning copper wheel positioned underneath the crucible, it is rapidly solidified and is thrown off the wheel as a thin solid ribbon, some mm wide and down to 20 μm in thickness.
Magnesium-based alloys are considered promising candidates for hydrogen storage for automotive applications due to their low specific weight, high hydrogen storage capacity (7.6 wt. %) and rich abundance of the Photo: Ying Wu constituent metals. Melt spun ribbons. In order to improve the applicability of magnesium, several methods as adding transition and rear earth metals have been employed to modify the reaction pathway and to enhance the H-sorption kinetics. In addition, rapid solidification has been employed to produce nano-sized grains and even amorphous microstructures to improve the hydrogenation characteristics.

Hence, research work on anode quality is therefore important.

The production of nanosized ceramic powders by spray pyrolysis
There are significant activities world wide related to the day. Since establishment we have produced a variety of development of ceramic materials. different compositions and the method has demonstrated its versatility producing high purity, homogeneous In particular there are substantial efforts associated powders with particle size less than 100 nm. The powders with improving the functional properties of a number of have shown excellent sintering properties resulting in multi component oxide based materials.

Materials with tailored catalytic properties are also important in a number of applications of significant industrial interest. These material systems have all in common that they are oxide based with rather complex compositions and materials processing is usually based on the availability of homogeneous, nano sized powders.
A particular powerful method to obtain ceramic powders with nano-homogeneity and nano-size combined with a high production rate is spray pyrolysis. The precursors are typically based on water soluble metal salts (e.g. nitrates) mixed in correct proportions and atomized using pressurized air and subsequently fed into a hot rotating chamber where drying and reaction takes place.
A complete pilot plant for powder production based Photo: Tommy Mokkelbost on spray pyrolysis is established at our department with Fig. 1: capacity to produce between 5 and 10 kilos of powder per Process steps for producing ceramic powders by spray pyrolysis.
