metal alloy

An alloy is a mixture of metals or a mixture of a metal and another element. Alloys are defined by metallic bonding character. An alloy may be a solid solution of metal elements (a single phase) or a mixture of metallic phases (two or more solutions).

  • Improving heating-based components with foam

    The energy efficiency of heat exchangers, convectors and cooling elements can be improved even further. Open-pore structures made of metal foam, which have good thermal conductivity and a large surface, offer interesting possibilities here. The BINE Projektinfo brochure entitled "Metal foam – a material for heat engineering" (11/2016) presents the development work for these materials. The aim is to optimise the manufacturing process, reduce costs and test the materials on test rigs. The material properties of the different alloys will be recorded in a database.

  • Innovation Day Laser Technology – Laser Additive Manufacturing

    Selective laser melting makes it possible to manufacture highly complex geometries made of magnesium and magnesium alloys in a flexible and precise way. LZH

    Smallest structures, complex parts or individual implants – due to its flexibility additive manufacturing has a high potential for use in modern production technology. Therefore, this topic is perfectly suited for the ”Innovation Day Laser Technology – Laser Additive Manufacturing” that is organized by NiedersachsenMetall and the Laser Zentrum Hannover e.V. (LZH) to transfer the latest research and development results to industrial application. On November 09th, 2016, small and medium-sized enterprises (SMEs) are invited to come to the LZH to inform themselves about laser-based additive manufacturing.

  • Legierungen werden fest und formbar

    Für die Stahlindustrie zeichnet sich womöglich ein Ausweg aus einem Dilemma ab, das schon solange besteht wie Menschen Metall verarbeiten. Wissenschaftler des Max-Planck-Instituts für Eisenforschung in Düsseldorf präsentieren einen neuartigen metallischen Werkstoff, der gleichzeitig sehr fest und trotzdem gut formbar ist. Bislang ließ sich die eine Materialeigenschaft nur auf Kosten der anderen verbessern. Das ändern die Düsseldorfer Forscher, indem sie einen neuen Weg beider Entwicklung von metallischen Werkstoffen gehen. So tragen sie dazu bei, dass sich Bauteile aus Metall künftig dünnwandiger konstruieren und dadurch Ressourcen schonen lassen.
