Abstract
The influence of cooling rate and heat treatment on the mechanical properties of Al-Si-Cu alloy castings made in gypsum molds were presented in the article. A series of identical T6 heat treated strength samples were made for three variants of mold temperature: 30 °C, 200 °C, 300 °C. The cooling rate in the thermal axis of the sample, the Dendrite Arm Spacing microstructure parameter were measured. Analyzed parameters were correlated with the obtained values of mechanical properties.
