ABSTRACT
Treatment of metal alloys is one of the ways to affect the properties of the material. The article describes an experiment realized at FPTM UJEP when was experimentally studied the influence of alloys AlSi9CuMnNi calcium modification on some of its properties. The alloy was modified with various amounts of calcium and subsequently machining. Also hardness was measured in the resulting alloys. Machining was performed under certain cutting conditions. After machining the obtained chip was evaluated. Chip was evaluated for its shape, length and amount of chips per 100 g. Devices in FPTM laboratories were used to prepare experimental casts and to evaluate hardness and chips, like the melting furnace LAC K70/13, hardness tester Ernst AT 250X or microscope Olympus SZX 10. Experimental quantities of calcium was 0.05, 0.1 and 0.15 wt. %. Presented experiments are part of the extensive research undertaken at Faculty of Production Technologies and Management at Jan Evangelista Purkyně University in Ústí nad Labem.
