Item Vplyv teploty formy na vybrané vlastnosti AlSi5Cu2Mg(University of Žilina, 2024) Kantoríková, ElenaCurrently, high demands are placed on the costs associated with the production of products, therefore it is advisable to know the individual characteristics of materials that are used in industry. The article deals with the influence of mold temperature on the mechanical properties of aluminium alloy. By knowing the characteristics of individual materials, it is possible to effectively design and manufacture equipment that will be safe and suitable for the given application. In many cases, aluminium alloys are offered as a solution, which are considered innovative construction materials, mainly because of the perfect combination of their properties.Item Tepelné spracovanie nástrojových ocelí(University of Žilina, 2024) Fabian, PeterThe article describes the importance of heat treatment of tool steels, referred to as class 19. To obtain the required properties of steels, their chemical composition alone is not enough. An irreplaceable role is also played by subsequent processing, be it thermal, chemical, or a combination chemical-thermal or thermo-mechanical processing. With the right settings processing, the desired properties are achieved, and the service life of the steel is also increased.Item Vplyv technológie tepelného spracovania na tribologické vlastnosti vybraných oceľových materiálov(University of Žilina, 2024) Harvanec, Jakub; Mičian, Miloš; Nový, FrantišekThe heat treatment technology changes all sorts of materials properties. We examined the change of tribological properties of selected powder metallurgy materials and conventional steels, in this article. We used special testing equipment, for measuring the changes of friction coefficient of individual tested materials, before application of the heat treatment and after application of the heat treatment. We tested two types of powder metallurgy steels and two types of conventional steels. The changes in friction coefficient are shown in the table and charts. We used boronising, nitriding and surface hardening as procedures of heat treatment.Item Vyvolanie scitlivenia na koróziivzdornej oceli 1.4845(University of Žilina, 2023) Kaličiak, Samuel; Kantoríková, Elena; Bolibruchová, DanaThe experiment is focused on the influence of heat treatment, solution annealing and subsequent sensitization of stainless steel 1.4845. In the experiment, a suitable thermal cycle of solution annealing and subsequent sensitization is designed. Subsequent comparisons of the microstructure and hardness of steel 1.4845 before and after the proposed heat treatmentItem Dodatočné spracovanie spekaných materiálov(University of Žilina, 2023) Kantoríková, ElenaPowder metallurgy is a method of producing materials and products with required properties and required exact shapes. The development of new materials contributes to this. The general advantage of powder metallurgy is the possibility of producing parts of complex and precise shapes in large series and optimized production costs, resulting from lower energy requirements compared to casting and chip machining.
