Against the background of the lightweight industry, the development of new aluminum alloys with high specific strength and low production cost is one of the main goals in modern industry. However, hot tearing is one of the most serious and irreparable defects in the production of thin-wall, complex and large castings of aluminum alloy, which limits the application of aluminum alloys [1][2][3] . Hot tearing is mainly attributed to insufficient feeding during solidification and the large-size thermal stress and strain at the end of solidification [4] . The fracture morphology shows that hot tearing usually occurs in the intergranular area, and the residual liquid or separated solid dendrite bridge is observed at the crack [4][5][6] .

“…The analysis method developed by Bäckerud [14] is one of the first that appears in the literature, while in recent years some researchers have conducted studies of this type in order to optimize the characteristics of parts made by casting using some variants [15,16]. There are some current works that use the patented UMSA simulator method (Universal Metallurgical Simulator and Analyzer Platform) [17,18] which design considerably reduced the thermal inertia and improved the thermal signal to the noise ratio.…”

Thermal analysis of a hypereutectic Al-Si alloy used for an automotive part was carried out in this research work. Solidification characteristics are recognized from the Temperature-time curve and its corresponding derivatives. This analysis was successfully used in a simulation software program with the aim of improving the resultant simulation accuracy. In this study, different types of molds, with and without cooling systems, were designed and used. The melt present in the furnaces of the factory was used to simulate the casting process. The effect of different cooling rates (1.2ºC/s, 2ºC/s, 2.3ºC/s and 2.9ºC/s) on the solidification parameters have been investigated. Differences in the resultant microstructure between wall and center of the molds have been analyzed and have been related to the T-t curve. Finally, the experimental results clearly indicate that the water-cooling rate of the molds and the melt temperature directly affects the solidification process as well as the final microstructure.

“…Ca and Sb in the role of modifiers can be considered relatively less common in the present area, Na and Sr are more commonly used. [4,5] Some types of aluminium alloys can be heat-treated. Heat treatment of aluminium alloys can be in the sense for CSN 42 0056 defined as the process by which a product or product parts in solid state is subjected to one or more cycles of annealing to achieve the desired structure or substructure and properties.…”

Treatment of metal alloys is one of the ways to affect the quality and properties of the material At the Faculty of Mechanical Engineering of the Jan Evangelista Purkyně University in Ústí nad Labem, one part of the research consists of searching for the influence of various modifying and inoculating elements on selected aluminium alloys. One of the alloys undergoing the present research is the hardening aluminium alloy AlSi9CuMnNi. The article describes one from these experiments, than AlSi9CuMnNi alloy was modified with various amounts of calcium (0.05, 0.1 and 0.15 wt. % Ca) and 0.2 wt. % Sb. The alloy without modification and with 0.2 wt. % Sb was heat-treated, too. In the experiment were made three castings for each type of alloy. Experimental samples were evaluated form view of final hardness, were machined, too and there were analysed tool wear of using cutting inserts and final ship from machining (turning). Presented experiments are part of the extensive research undertaken at FME at JEPU in Ústí nad Labem.
