Investigations of the Distribution of Elements in Phases Present in G-AlMg sub 5 Si Cast Alloy With EDX/WDX Spectrometers and AES

The mechanical properties of most Al alloys depend heavily on chemical composition, casting methods and heat treatment.

Summary:The mechanical properties of most Al alloys depend heavily on chemical composition, casting methods and heat treatment. Alloys of type G-AlMg sub 5 Si are known for good corrosion resistance and mechanical properties at elevated temperatures. Under the designation Hydronalium (Hy 511) they are used for the production of heads for air cooled Diesel engines. To obtain better mechanical characteristics, Ti is added to the alloy. This paper deals with the results obtained during investigations of the distribution of elements in binary eutectic ( alpha , Mg sub 2 Si) and ternary eutectic alpha , Si, Mg sub 2 Si) as well as the distribution of Ti in samples of Hy 511, obtained during casting of cylinder heads. Studies of the distribution of the elements were performed using EDX/WDX spectrometry, and the distribution of Ti was studied also with Auger electron spectroscopy.
