Experimental Study of Correlation of Mechanical Properties of Al-Si Casts Produced by Pressure Die Casting with SiFeMn Content and Their Mutual Mass Relations

الملخص EN

The submitted contribution addresses problems concerning influence of alloying elements (Si/Fe/Mn) of Al-Si pressure die casts (HPDC) on values of residual deformation.

On the basis of results of executed experiments, mutual correlations are analyzed and described, while not only measurements results are evaluated but also metallographic outputs of obtained compounds from the view of their formation, occurrence, and size.

The development of intermetallic phases structures Al(FeMn)Si as well as intermetallic ferritic phase Al3FeSi was observed.

More verification experiments follow in order to apply obtained knowledge for improvement and/or preservation of casts properties on required level.
