Abstract (en)
[origin: WO2020102832A1] The invention relates to a component (8) having a solid structure, manufactured by a laser- or electron beam in an additive manufacturing process, from at least one material selected from a group comprising molybdenum, a molybdenum-based alloy, tungsten, or a tungsten-based alloy, and relates to a component (8) having a solid structure, manufactured by a laser- or electron beam in an additive manufacturing process, from at least one material selected from a group comprising molybdenum, a molybdenum-based alloy, tungsten, a tungsten-based alloy and a molybdenum-tungsten based alloy, said component (8) having one or more alloying element(s) which has or have - in the case of molybdenum and the molybdenum-based alloy a reductive action on MoO2 and/or MoO3 -<sb />, in the case of tungsten and the tungsten-based alloy a reductive action on WO2 and/or WO3 , and - in the case of the molybdenum-tungsten based alloy a reductive action on at least one oxide of the group containing MoO2 and/or MoO3 , WO2 and WO3 , at least in the temperature range ≥ 1500 °C, the alloying element or at least one of the alloying elements being present both in at least partially non-oxidised form and oxidised form.
