The resulting alloys were porosity-free with good contacts between the particles. The structures were very fine and consisted of primary alpha(Al) dendrites, eutectic silicon and the betha-Al5FeSi phase. The Vickers hardness values of the Al-14Si-8Fe and Al-22Si-8Fe-1Cr alloys were (170 10) HV5, (185 16) HV5, respectively. Compressive strength values were 670 MPa and 720 MPa, respectively. Surprisingly, both alloys exhibited a very good plasticity due to the refined structure. The alloys were annealed at 300-400 °C for 100 h to reveal their thermal stability. When the thermal stability of the powder-metallurgy Al-14Si-8Fe and Al-22Si-8Fe-1Cr alloys was compared to that of the casting-piston Al-12Si-1Cu-1Mg-1Ni alloy, the former was found to be superior"},{"@xml:lang":"sl","#text":"Zlitini Al-14Si-8Fe in Al-22Si-8Fe-1Cr (w/%) sta bili pripravljeni s centrifugalno atomizacijo in hladnim enoosnim stiskanjem s tlakom 6 GPa.
