  text: <jats:p>Abstract. In order to reduce global energy consumption in production
    and industry along with the associated CO2 emissions, existing resources must
    be used more efficiently. This includes the energy-efficient and comprehensive
    recycling of a wide range of metals. Especially for the production of aluminium,
    there is a large potential for saving energy using efficient recycling processes.
    With regard to the recycling of aluminium studies have shown that solid-state
    recycling processes are significantly more efficient considering the used energy
    and resources compared to the conventional, smelting-metallurgical recycling process.
    In this paper, the direct and energy-efficient friction-induced recycling process
    (FIRP) based on the conform process is further described and analysed in terms
    of the temperature-property relationships. For this purpose, the influence of
    the processing temperature on the microstructure and properties of the recycled
    semi-finished products is investigated using the toll system that enables an ECAP
    forming. Specific sections of the (in theory) infinite, recycled semi-finished
    product are taken and analysed at different process temperatures of the solid
    state recycling process. Based on these sections, the properties in terms of mechanical
    hardness, strength, ductility and grain size are analysed and a degressive relationship
    between process temperature and mechanical hardness up to a temperature of 270
    °C can be shown. Applying the Hall-Petch relationship, it is analysed whether
    there is a correlation between the strength and the microstructure in the form
    of the grain size. </jats:p>
