Process for producing an iron-aluminium intermetallic alloy and iron-aluminium intermetallic alloy

摘要

An intermetallic iron-aluminum alloy is produced by hot pressing a degassed powder mixture of iron, aluminum and optionally other components. Independent claims are also included for the following: (i) an intermetallic iron-aluminum alloy containing zirconium, boron and yttrium oxide and having an elongation of 1.5% and an elastic limit of 960 MPa, the alloy being produced as described above; (ii) an intermetallic iron-aluminum alloy containing zirconium, boron and yttrium oxide and having an elongation of 0.2-0.8% and an elastic limit of 1240 MPa, the alloy being produced as described above; and (iii) an intermetallic iron-aluminum alloy element produced as described above.
