Opis:
Modification of alloys is an important part of the metallurgical process, and this also applies to aluminum alloys, particularly for Al-Si (silumins). As a modification of the material we can utilise the modification using the selected element or heat treatment of alloys, or a combination of both processes. One of the elements that it is possible to modify the alloy of Al-Si used is antimony (Sb). The paper examines the possible effect of the modification of that element and heat treatment on the final structure of the alloy AlSi9CuMnNi and other selected properties after machining. In the experiments three castings from the alloy AlSi9CuMnNi were made without modification, three castings with the modification and without heat treatment, three castings with modification and without heat treatment, and three castings with modification and heat treatment. The described experiment and analysis are part of extensive research undertaken at Faculty of Production Technology and Management, J. E. Purkyně University in Ústínad Labem.

Opis:
Al Alloys have an important position in the industry, mainly in the automotive and aerospace industries. One important group is silumins (Al-Si alloys). Al-Si alloys are the leading casting alloys based on aluminum. Machining of aluminum alloys is currently frequently used and it is an important area of production. This paper deals with an experiment that was conducted at the Faculty of Production Technology and Management, University of Jan Evangelista Purkyně in Ústí nad Labem, where alloy AlSi7Mg0,3 was experimented upon. Samples were made for processing from the master alloy AlSi7Mg0,3, subsequently unmodified and modified of Sr, Ca and Sb. This paper describes the evaluation of hardness, chip and tool wear in terms of how modification by Sr, Ca and Sb may affect analytical values.

Opis:
The use of secondary aluminum alloys is increasing because it contributes to the decrease of production costs. However, these alloys contain bigger amount of iron. Iron has a negative effect and therefore its elimination is necessary in order to add some elements, which are also called correctors of iron. The most frequently used corrector is manganese. Another quite often used correctors are chromium, potassium, magnesium, vanadium. In the following work, vanadium is used as a corrector of iron phases. The application of vanadium in aluminum alloys has a positive impact on their mechanical properties, increases the tensile strength, ductility and hardness. As experimental material AlSi6Cu4 alloy was used. It was alloyed by master alloy AlFe10. After adding to the master alloy the iron content, the critical value in the alloy exceeded. Vanadium was added to AlSi6Cu4 alloy in different quantities. The image analysis (software NIS-Elements) was used for quantifying the amount of iron based intermetallic phases and determination of average values.
