“…Simulation software for heat treatment Based on the above assumptions and regularities, it is clear that the primary requirement for the technological process of heat treatment is its rationality, ie. that the required properties will be achieved without unnecessarily increasing costs and time losses [12,13].…”

The concrete, as material commonly used in construction, has been the subject of research for many years in order to improve the properties. One way to improve is to use the steel fibers. In the paper a comparative analysis of selected mechanical properties for concrete and fiber-reinforced concrete, e.g. compressive strength and Young's modulus, was presented. It was checked how the value of Young's modulus and the compressive strength of concrete change depending on the content of steel fibers. Three types of samples were prepared and tested: 1 -concrete, 2-fiber-reinforced concrete containing 0.25% of steel fibers, 3-fiber-reinforced concrete containing 0.50% of steel fibers. The conducted research was to show composition of which sample is the most advantageous and how many fibers should be used to obtain the mechanical properties, in this case compressive strength and Young's modulus, the best. The research covered the preparation of concrete samples, their curing and seasoning, measurements of Young's modulus and compressive strength with the use of a strength press, as well as the analysis and interpretation of the obtained results. As the analysis has shown, the greater number of steel fibers is not directly proportional to the increase in its compressive strength or the value of Young's modulus.

“…components for the needs of the automotive and aerospace industries [8,9]. The current trend in the automotive industry is the use of Al-Si-based suprautectic alloys to produce engine blocks and cylinders for combustion cylinders engines [10,11]. Among their main disadvantages in the casting process include the formation of crops, segregation of silicon particles and coarse eutectic structure [12].…”

This study focuses on surface treatment of aluminium alloys by High Speed Steel (HSS30) via Plasma Transferred Arc. The main motivation of this research has been an assignment of local company in order to prolong the lifetime of a tire press molds, especially the interface of its segments. These segmented molds are made from aluminium alloy and their interface is exposed to multiple percussions, which leads to cracks. Therefore, PTA surfacing is considered as a suitable surface treatment for hardening its interface, yet benefit from lightweight of aluminium matrix. For purposes of this research AlSi9CuNiMn alloy was used as a matrix metal. Permeation in the contact zone was examined via confocal and scanning electron microscope. Hardness of affected matrix area was measured by using Vickers Hardness Tester.
