“…From among MMCs, those perceived as particularly attractive and most intensively developed are particulate reinforced metal matrix composites (PRMMCs) based on lightweight aluminum alloys (aluminum matrix composites, AlMCs) reinforced with hard ceramic phase, especially with particulate silicon carbide (SiC p ). A number of authors [6][7][8] pointed out that compared to the matrix material, Al/SiC p composites are characterized with higher strength and rigidity, also at elevated temperature, better stability of the thermal coefficient of expansion, and increased hardness and resistance to abrasive wear. Due to a number of favorable properties, the composites can successfully substitute monolithic materials such as aluminum alloys or iron alloys in applications involving operation in difficult and complex conditions, especially in tribological couples of various types.…”

The scratch test enables assessing the susceptibility of a material to the development of scratches and, being in some ways a measure of its abrasion resistance, allows extended knowledge in the field of material application usability, especially its machining capabilities. The aim of the study was to assess the resistance of a centrifugally formed AlSi12/SiCp composite layer with a high share of reinforcing phase (Vp > 40%) to scratching with a diamond indenter. The microstructure and effect of the load applied to the diamond indenter on the scratch depth and susceptibility of the composite layer to the nucleation and propagation of cracks in hard and brittle SiC particles were analyzed. A simple model of SiCp cracking depending on their size, shape (geometry), and orientation in relation to the direction of scratching has been proposed.

“…In metal matrix composite (MMCs), the distribution and the kind of particles i.e. size and shape as well as interface between reinforcing particle and matrix has very important effect on the utilization mechanical properties of materials such as: Al/TiC, Ni 3 Al/WC, Ni 3 Al/ZrC, Ni 3 Al/NbC, Ni 3 Al/TaC, Ni 3 Al/TaB or A339/SiC [12,21]. Transmission electron microscopy (TEM) is very useful tool for microstructural investigations of interfaces between particles and matrix in the MMC.…”

Refinement is one of the most energy consuming technological process, aimed at obtaining mineral raw materials of the proper grain size. Cast structural elements such as jaws or hammers in crushing machines operate under conditions of an intensive wear. The data indicate that 80 % of failures of machines and devices is caused by wearing of rubbing surfaces. This problem became the subject of several scientific and industrial investigations carried out in the whole world in order to produce materials ultra-wear resistant. Methods allowing to obtain wear resistant composite castings are discussed in the hereby paper. Within the performed research microstructures of the produced composite zones were presented and the comparative analysis with regard to mechanical and functional properties of local composite reinforcements in relation to the commercial alloys of increased wear resistance was performed. The results show almost twenty five times increase in wear resistance compared to manganese cast steel containing 18 % Mn.

“…Mahmoud et al [9] revealed that the SiC particles were distributed more homogeneously in the nugget zone, of an A1050-H24 aluminium plate, by using square probe tool than other shapes. Kurtyka et al [10] explained the influence of the plastic deformation generated in friction stir processing on the changing concentration and distribution of SiC reinforcement particles in the cast composite A339/SiC/p, as well as determined its mechanical properties. Sathiskumar et al [11] reported that in Cu/B 4 C surface composite, the SZ area with B4C particles was reduced as compared to the SZ area in FSP of copper without particles.…”

The paper presents the results of friction stir processing (FSP) process of cast aluminium alloy AlSi9Mg. The studies included a modification of the microstructure in the grain refinement, elimination of voids and the production of composite material AlSi9Mg + Re. Rhenium is famous for its refractory character, high density as well as high hardness. It is well known as alloying element for improvement of strength, plasticity, weldability, reduction of the degree of recrystallization embrittlement mainly in W, Mo and Ni based alloys. Re is used in superalloys as a solid-solution strengthening alloying element and increasing corrosion resistance at high temperatures. Rhenium containing alloys have high electrical resistivity and refractory character. The modification was carried out single-and multiple runs. The results show significant fragmentation in the mixing microstructure, and a metallic continuity. Fragmentation in the mixing microstructure was confirmed by SEM research. The study revealed that mechanical alloying technology FSP allows to increase the hardness of the material. The ability to produce graded materials AlSi9Mg alloy matrix by frictional treatment is also indicated.
