DUCTILE FAILURE IN STANDARD SILUMINS

With a view to economy in metal consumption, it is appropriate to make wider use of cast aluminum alloys instead of worked alloys, particula rly for the production of critical components. It is thus necessary th at the castings have a high level of mechanical properties, particular ly ductile failure, since the reliability of aluminum alloy components depends on this property. The current paper presents the results of r esearch into the ductile failure and structure of silumins in the cast condition and after heat treatment.
