Abstract (en)
[origin: WO2017013087A1] The invention relates to a process for manufacturing a part made of an Al/Al3B48C2 composite material comprising an aluminium matrix in which particles of a mixed carbide of chemical formula Al3B48C2 are dispersed. The process comprises the following steps: a) placing a powder of chemical formula AlB2 in the cavity of a graphite crucible; b) closing the cavity with a graphite element; c) heating the crucible at a temperature at least equal to 960°C and less than or equal to 1400°C in order to obtain the formation of precipitates of the mixed carbide of chemical formula Al3B48C2 in liquid aluminium; d) cooling the crucible in order to solidify the liquid aluminium; e) removal from the crucible; by which means the part made of Al/Al3B48C2 composite material is obtained.
