In the paper is presented an attempt of assessment of melting and modification effect on Rm tensile strength of Al-Si alloys poured into metallic moulds. Investigated alloys underwent refining and modification with AlSr10 master alloy. Run of the crystallization process was presented with the help of solidification curves, making use of thermal-voltage-derivative analysis (ATND). Obtained results comprise registered curves of solidification, strength tests, microstructure of the alloy and regression analysis. On base of performed regression analysis one obtained a dependencies enabling evaluation of Rm tensile strength of Al-Si alloys as early as on stage of their preparation (melting).

W pracy przedstawiono próbę oceny wpływu warunków procesu topienia i modyfikacji na wytrzymałość na rozciąganie Rm stopów Al-Si odlewanych do form metalowych. Stopy Al-Si poddano rafinacji i modyfikacji zaprawą AlSr10. Przebieg procesu krystalizacji charakteryzowano za pomocą krzywych krystalizacji. Stosowano metodę analizy termiczno-napięciowo-derywacyjnej (ATND). Wykonano próbę statyczną rozciągania oraz badania mikroskopowe wytworzonych stopów Al-Si. Analiza regresji stanowiła podstawę do uzyskania zależności pozwalającej określić prognozowaną wytrzymałość na rozciąganie Rm stopów Al-Si w procesie topienia i krystalizacji.
