The invention relates to the reduction of core losses in soft magnetic applications utilizing amorphous foil as the core material. Amorphous foil is known to have lower losses when compared to crystalline silicon steel laminations. It is found that a reduction of 10-40% of losses can be achieved over the current state of the art amorphous material by mechanical scribing of the surface of the soft magnetic laminations comprising the wound core in power conditioning devices such as a transformer. The scribing process introduces control of the magnetic domains causing ease of magnetic flux reversal.

The present disclosure relates to an aluminum alloy material, and specifically to a weldable in-situ nano-strengthened rare-earth metal (REM)-containing aluminum alloy with high strength and toughness and a preparation method thereof. In the present disclosure, in-situ nano-ceramic particles and REMs simultaneously introduced into an AlZnMg alloy can effectively refine the grains and significantly improve the strength and toughness of the alloy; and REM-containing nano-precipitated phases and in-situ nanoparticles distributed in the grains or at grain boundaries can also significantly increase a recrystallization temperature of the alloy, effectively inhibit the dynamic recovery, reduce the re-dissolution of alloying elements, and improve the weldability of the alloy.

A method and apparatus for producing solid alloy components from its liquid state are provided. The molten alloy is rapidly cooled using a chill to temperatures below the thermosolutal transition temperature of the alloy. Finite-amplitude acoustic vibration is applied on the chill to shake off dendrites that form on the chill surface, to stir the slurry containing the fragments of dendrites, and to shake off slurry material that sticks on the surface of the chill as the chill is separating from the slurry. The slurry is then immediately poured into a chamber of a forming machine or a mold cavity shaped into solid components.
