“…The new members of the ZA casting alloy family are ZA8, ZA12, and ZA27 [1]. Among these alloys, ZA27 exhibits attractive physical and mechanical properties combined with high tensile strength and wear resistance properties, making it a bearing alloy as replacement of their conventional counterparts like aluminum casting alloys, bearing bronzes, and cast iron in various engineering applications [2][3][4][5][6]. To meet the growing demands for application of these alloys in industry, further investigations on the correlations among the thermo-mechanical process parameters, the microstructure evolution of the materials, and the mechanical properties need to be considered [7][8][9][10][11][12][13][14].…”

The hot deformation behavior of ZA27 alloy was investigated in the temperature range of 473-523 K with the strain rates in the range of 0.01-5 s -1 and the height reduction of 60 % on Gleeble-1500 thermo mechanical simulator. Based on the experimental results, constitutive equations incorporating the effects of temperature, strain rate, and strain have been developed to model the hot deformation behavior of ZA27 alloy. Material constants, a, n, ln A, and activation energy Q in the constitutive equations were calculated as a function of strain. The results showed that the stress-strain curves of ZA27 alloy predicted by the constitutive equations are in good agreement with experimental results, which validates the efficiency of the constitutive equations in describing the hot deformation behavior of the material.

INFLUENCE OF HEAT TREATMENT ON THE WEAR RESISTANCE OF THE ZnAl40Cu1.5Ti1.5 ALLOYZn-Al-Cu alloys are predominantly used due to their tribological properties. One of the crucial issues related to the use of Zn-Al alloys is their dimensional instability. Partial replacement of copper with titanium greatly contributes to the reduction of the dimensional instability issue. The study involved the ZnAl40Cu1.5Ti1.5 alloy. In this work, microstructure and wear properties of ZnAl40Cu1.5Ti1.5 alloy were studied in both as-cast and heat treated conditions. The heat treatment was performed by solution treatment at a temperature of 385°C for 24 hours, quenching in cold water and artificial aging at 125°C for 3 hours. The hardness tests enabled to specify the optimum ageing time span, which amounts to 3 hours. Wear tests indicated that the ZnAl40Cu1.5Ti1.5 alloy is characterized with high wear resistance. It was also observed that the applied heat treatment increases the wear resistance of the experimental alloy.

Zn-Al alloys are mainly used due to their high tribological and damping properties. A very important issue is determination of the hardness of the phases present in the Zn-Al-Cu alloys. Unfortunately, in literature there is lack of studies on the hardness of the phases present in the alloys Zn-Al-Cu. The aim of this research was to determine the hardness of the phases present in the ZnAl22Cu3Si and ZnAl40Cu3Si alloys. The scope of the research included examination of the structure, chemical composition of selected micro-regions and hardness of phases present in the examined alloys. The research carried out has shown, that CuZn 4 phase is characterized by a similar hardness as the hardness of the interdendritic areas. The phases present in the structure of ZnAl40Cu3 and ZnAl22Cu3 alloys after soaking at the temperature of 185 O C are characterized by lower hardness than the phase present in the structure of the as-cast alloys.Keywords: ZnAl22Cu3 alloy, ZnAl40Cu3 alloy, nanohardness, structure Stopy Zn-Al stosowane są przede wszystkim z uwagi na swoje wysokie właściwości tribologiczne i tłumiące. Bardzo ważnym zagadnieniem jest określenie twardości faz występujących w stopach Zn-Al-Cu. W literaturze brak jednak opracowań dotyczących twardości faz występujących w stopach Zn-Al-Cu. Celem przeprowadzonych badań było określenie twardości faz występujących w stopach ZnAl22Cu3Si oraz ZnAl40Cu3Si. Zakres badań obejmował badania struktury, składu chemicznego w wybranych mikroobszarach oraz badania twardości faz występujących w badanych stopach. Przeprowadzone badania wykazały, że faza CuZn 4 charakteryzuje się zbliżoną twardością do twardości obszarów międzydendrytycznych. Fazy obecne w strukturze stopów ZnAl22Cu3 oraz ZnAl40Cu3 po wygrzewaniu w temperaturze 185• C charakteryzują się mniejszą twardością niż fazy obecne w strukturze stopów w stanie po odlaniu.
