Abstract

The use of silumins as construction materials in mechanical and aircraft engineering is often limited due to the presence of large crystals of intermetallic phases of the Al–Si–Fe and Al–Si–Fe–Mn systems in their structure. This paper shows the formation of iron-containing intermetallic phases in Al–12%Si by using tungsten addition in amount 0.01–0.5 mass%. It has been found that introduction of 0.01 mass% W leads to the transition of the needle-shaped β-phase into the α-phase having more compact blocky form and polyhedral crystals, with a decrease in the dimensions of the α-phase by more than 2 times. The addition in amount of 0.05, 0.1, and 0.5 mass% W leads to the decrease in the dimensions of α- and β-phases by an average of 1.5 times. The change in the formation of iron-containing intermetallic phases in Al–12%Si alloy after the tungsten addition leads to an increase in mechanical properties by an average of 20%.
