“…3 or better An analysis of material selection for the construction of rocker arms was made for the following designated alloys: 204.2 (AlCu4TiMg), 357 T6 (AlSi7Mg0.6), and 7075 (AlZnMgCu). A comparative analysis was carried out on the basis of the available literature for the selected alloys with reference to the strength requirements for the construction presented in Table 2 [8,9,10,11]. The results of the comparison shown in Table 3, i.e.…”

The new research trends are moving away from research works that are not directly connected with industrial applications. The Integrated Computational Materials Engineering (ICME) is an excellent example of the relationship between scientific research and the industrial sector.As an example of the design development of construction of a suspension component, an overview of the changes of a welded part replaced with cast component is presented. The identification of boundary conditions and forces operating on the nodes of the suspension element allowed determining the critical areas in the existing welded construction. Then the new design of casting for high performance applications was developed. Analysis of the kinematics of the suspension components also revealed the need for changes in the design of the mounting points of the suspension components to reduce the maximum values of forces and enforced moments. As a result of successive stages of the topology optimization of analysed cast, control arms with significantly lower values of maximum stresses were obtained. The material conversion of welded part with high strength AlZnMgCu aluminium alloy allowed the reduction of the weight by 25% for the lower control arm and 30% for upper control arm.

“…Additionally, the specific mechanism of grain refinement may differ depending on the alloy structure and interaction among titanium and other elements in the alloy. For example, in aluminium alloys, titanium forms certain intermetallic compounds that additionally serve as effective nucleation spots [2,[5][6][7]. Titanium additive to zinc alloys may be analysed with the use of the phase equilibrium systems.…”

The paper presents the possibility of the industrial production of Zn4Al3Cu alloy with the addition of 0.41% Ti. Tests are described on the manner of introducing the ZnTi2 master alloy to the alloy, so that the chemical composition of the desirable elements proportion is obtained. The chemical persistence of the Zn4Al3CuTi was determined as low in the conditions of the long heating of the alloy before casting. Tests on the microstructure and mechanical properties of the obtained alloys were also conducted. The strength of the die-cast Zn4Al3Cu alloy was 265 MPa and, when measured on samples taken from the high pressure die-cast, it reached 369 MPa. It was determined that the addition of titanium to the Zn4Al3Cu alloy causes significant refinement of the structure and contributes to the formation of intermetallic phases.

“…Microstructure characteristics are an important factor in the wear resistance of alloys [12][13][14][15]. The abrasion resistance of alloys can be improved by increasing the hardness of an alloy, which can be accomplished by disintegrating its microstructure, including eutectics and eutectoids.…”

The paper presents the results from a study on the impact of the cooling rate in the eutectoid transition on the abrasive wear of the as cast Zn-4Al alloy. The microstructure of the researched material consists of dendrites of the η solid solution and an (α+η) eutectic structure. During the eutectoid transformation at 275 o C the distribution in the eutectic structure was transformed and fined. Heat treatment was carried out for this alloy, during which three cooling mediums were used, i.e. water, air and an furnace. For the research material obtained in this way, metallographic examinations were performed using the methods of light and scanning electron microscopy, as well as hardness measurements. It was found that faster cooling rate promoted the fragmentation of structural components, which translates into higher hardness of the material. This also had effects in the tribological wear of the tested alloy. As part of the tests, an abrasive wear test was carried out on a standard T-07 tester.
