"The article deals with measurements dependence of coefficient of thermal contraction on chemical compound of Al-Si alloys, so-called silumin, during their solidification and cooling. For this purpose the measuring apparatus, which applies a dilatometer, measuring frame, casting mould with cavity \u00C6 60 x 70 mm and PC, was made up. Dilatation curves of pure Al and Al alloys were acquired during the casting process and noted by computer. Melts were metallurgical treated with the refining salt before casting into the moulds. We observed the influence of chemical compound of melt on coefficient of thermal contraction, which was computed from obtained dilatation curves." . "2010-05-18+02:00"^^ . "251864" . . .
