Abstract
Casting core for the manufacture of hollow metal aeronautical parts, in particular high-pressure turbine parts by lost-wax casting, including a composite material including on the one hand a first phase of formula Mn+1AlCn, where n=1 to 3 and M being a transition metal selected from the group consisting of titanium and/or niobium and/or molybdenum, the composite material including on the other hand a second phase of formula Al4C3.
Claims15
A casting core for the manufacture of hollow metal aeronautical parts comprising a composite material comprising on the one hand a first phase of formula Mn+1AlCn, where n=1 to 3 and M being a transition metal selected from the group consisting of titanium and/or niobium and/or molybdenum, the composite material comprising on the other hand a second phase of formula Al4C3.
A method of manufacturing a casting core for making a hollow metal aeronautical part the casting core comprising a composite material comprising, on the one hand, a first phase of the formula Mn+1AlCn, where n=1 to 3 and M being a transition metal selected from the group consisting of titanium and/or niobium and/or molybdenum, the composite material also comprising a second phase of formula Al4C3, the casting core being obtained by a powder metallurgy process comprising a mixing step in which powders for obtaining the composite material are mixed, and a shaping step.
