“…Zn-Al alloys show unique physical and structural properties. [1][2][3][4] Due to their relatively low melting point (about 400°C) and good castability, [5][6][7] Zn-Al alloys are common used for various industrial areas and mostly processed by some casting methods 8,9 like high-pressure die casting (HPDC). 10 More specifically, they are used in production of both structural and accessory parts for automotive, electrical and electronic industries as well as machinery and equipment requiring high manufacturing accuracy.…”

“…However, Zn-Al alloys have only limited ductility at room temperatures 3,4,13,14 and suffer from a distinct drop in strength at high temperatures. 2,4,15 To overcome these disadvantages, many attempts have been made to stronger Zn-Al alloys by the addition of alloying metals, such as Cu, Mg, Ni, Si, Ti and Zr. [16][17][18][19][20] Copper is often used to strengthen these mechanical properties of Zn-Al alloys [21][22][23][24] (all compositions are given in wt% unless otherwise noted).…”

In the present work, microstructure and mechanical properties of Zn-7Al-3Cu (wt%) ternary alloy are investigated depending on the temperature gradient and growth velocity. The alloy was prepared in the designated composition in a vacuum melting and casting furnace and then filled into the graphite sample moulds. The samples were directional solidified with various temperature gradients (6.7-10.7 K/mm) at a constant growth velocity (16.4 lm/s) and with various growth velocities (8.3-166.0 lm/s) at a constant temperature gradient (10.7 K/mm) in a Bridgmantype furnace. Microstructural images of solidified samples were taken with light microscope and scanning electron microscope. Eutectic spacings were measured from these images. Microhardness, ultimate tensile strength, yield strength and modulus elasticity values of each sample produced at various solidification parameters were also measured. The effect of temperature gradient and growth velocity on the eutectic spacing, microhardness, ultimate tensile strength, yield strength and modulus elasticity was determined using linear regression analysis. While the microhardness, ultimate tensile strength, yield strength and modulus elasticity values increased with increasing temperature gradient and growth velocity values or decreasing eutectic spacing, the elongation values decreased. Fractographic results show that the type of fracture is brittle.

“…Zn-Al alloys have been found to be a promising energy and cost effective substitute to a certain extent plain bearings. Zn-Al alloys exhibit high specific strength, excellent wear resistance, good casting properties and lower coat compared to other nonferrous metals [1]. The addition of Cu to the eutectoid Zn-Al alloys improves its mechanical properties, creep resistance and corrosion behavior [2,3].…”

Zn-30Al-xCu (x=0, 1, 2, 4) alloys were prepared by the spray atomization and deposition technique. The microstructures of the spray-deposited alloys were investigated by means of scanning electron microscope, transmission electron microscope, X-ray diffraction. The results indicate that the 1 wt. % Cu addition to spray-deposited Zn-30Al alloy does not make significant change in microstructure. However, with the 2, 4 wt. % Cu additions to the alloy, some ε-CuZn4 compounds with particle or irregular shapes were observed on the grain boundaries in the microstructures. Tensile test results confirmed that the 1 wt. % Cu addition displays superior tensile strengths, whereas the 2, 4 wt. % Cu additions led to the decreasing of the improvement effect of the tensile strengths.

“…The Zn-Al alloys have been found to be a promising energy and cost effective substitute to conventional bearing bronzes under heavy load and slow-to-medium speed applications [1,2]. In addition, these alloys have found increasing use for many applications and compete effectively against copper, cast irons, steel fabrications and aluminum alloys [3]. The eutectoid Zn-Al alloys have been modified by the addition of many elements in order to improve the mechanical and tribological properties and corrosion resistance [4].…”

In this study, the Zn-30Al-1Cu (wt%) alloy and TiB2/Zn-30Al-1Cu composite were synthesized by the spray atomization and deposition technique. The microstructures and mechanical properties of the spray deposited alloy and composite were studied using scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and tensile tests. The results have shown that the TiB2 particulates are formed in the microstructure. It was found that the in situ TiB2 particles can refine effectively the grain of the matrix and restrain the grain growth. The tensile test results indicate that the spray-deposited TiB2/Zn-30Al-1Cu composite has better strength than the Zn-30Al-1Cu alloy at room and elevated temperature (150°C) due to the presence of in situ TiB2 particles.
