METHOD FOR PRODUCING ALUMINUM ALLOY PARTS |
摘要 |
<p>The invention relates to an aluminum alloy part. The part comprises a multi-phase alloy comprising a plurality of complex large-cell metal phases, except for face-centered cubic (fcc) aluminum, said multi-phase alloy having a hardness greater than 300 Hv, a degree of porosity less than 5%, and a density less than 4.5 g.cm-3. The part is obtained by a method comprising melting a pre-form by sintering a mixture comprising an aluminum alloy powder and a polymer binder powder, said sintering being followed by removing the binder, then infiltrating the perform thus obtained with an infiltrating agent comprising liquid aluminum or a liquid aluminum alloy, characterized in that the aluminum alloy used to manufacture the pre-form is a quasi-crystalline aluminum alloy.</p> |
