“…It is known that the friction and wear properties of metals and alloys show a strong correlation with their chemical composition, hardness and microstructure. The objective of this paper is to analyse the possible correlations between the microstructure and the wear properties of low alloyed, hypoeutectoid structural steels during dry friction [1][2][3]. It became clear that for the experimental purposes special testing equipment is needed, which does not initiate changes in the original microstructure of heat treated steels specimens during the wear tests.…”

It is known that the friction and wear properties of metals and alloys show a strong correlation with their chemical composition, hardness and microstructure.The aim of this work was to analyse and evaluate the correlations between the microstructure and the wear properties of low alloyed, heat treated structural steel during dry friction. Three kinds of hypoeutectoid structural steel with different microstructure were studied. For experimental purposes, a new type of micro-scale, ballcratering tribometer and a proper wear-kinetic model based on an ordinary differential equation have been constructed. It was verified that if the process parameters (load, angular speed) are constant, the solution of the wear-kinetic differential equation could be expressed in a simple, closed form. Additionally, it was shown that (i) the heat treated steels have the highest wear resistance if the microstructure consists of only one hard martensitic phase, (ii) in case of microstructures consisting of two different phases (ferrite-pearlite, bainite, and spheroidite) the wear resistance decreases in the following order: bainite, ferrite-pearlite, and spheroidite.

“…On a macroscopic scale, the cost of materials is extremely important. Production of quality materials in conventional form is very well controlled and relatively cheap, even in the case of metal composite materials [1][2][3][4]. By moving from macroscopic engineering applications to precise and specialized products, production costs become less and less important, and more and more roles take over the properties of the materials produced.…”

The paper presents results of research for volumetric amorphous alloys Fe 61+x Co 10-X Y 8 W 1 B 20 where x = 0,12 in the shape of plater of 10mm x 5mm x 0.5mm diameter. Amorphous Samales were annealed at 953K for 10 minutes what caused their partial crystallization. As a result of the thermal interference in the volume of alloys, three different crystalline phases were formed aFe, Fe 5 Y and Fe 3 B. For samples after solidification and after thermal treatment thermomagnetic studiem were conducted. For amorphous alloys, only one ferroparamagnetic transition was visible, and for the alloys after the isothermal annealing process there were two inflections on the curve .µ 0 M s (T) corresponding to the two Curie temperatures. These intersections came from two amorphous phases. As a result of the research, it was found that these alloys crystallized in the primal crystalization. Crystallization was the reason for the increase of the first Curie temperature of the amorphous matrix while retaining its decrease with cobalt additive. The value of the second Curie temperature in the alloys after heating was found to depend mainly on the size of the crystallization products and in particular on the Fe 5 Y crystallite size.Conventional polycrystalline alloys are one of the most widespread materials in the world. Structures of countless grades of steel or aluminum are virtually impossible to replace by any other materials. On a macroscopic scale, the cost of materials is extremely important. Production of quality materials in conventional form is very well controlled and relatively cheap, even in the case of metal composite materials [1][2][3][4]. By moving from macroscopic engineering applications to precise and specialized products, production costs become less and less important, and more and more roles take over the properties of the materials produced. In many industries, emphasis is placed on selected properties. Magnetic properties are extremely important for different applications. At this point, polycrystalline materials often do not have satisfactory properties In this field. The answer to the search for materials that meet the high demands on the magnetic properties of alloys are rapid cooled materials [1,[5][6][7][8][9][10]. Despite the identical chemical composition, these materials have completely different properties than their crystalline counterparts. Research on this type of material has been going on for several decades. The beginnings of quick-cooled alloys were not impressive. Despite the good magnetic properties, the problem was the form of material obtained. The first alloys for which an amorphous structure was obtained were made in the form of tapes of thicknesses of around 50 µm. The liquid melt casting method on the rotating cylinder allows very high cooling rates (10 5 -10 6 K/s) what gives a very good chance of obtaining an amorphous structure for many chemical compositions [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. Unfortunately, this small dimension drastically limited the abi...
