“…As a result of the frictional heat and plastic deformation during FSW, coarse grains in the base metal transformed into fine equiaxed grains. Based on the fine and equiaxed grains in the NZ of the joints, it can be concluded that dynamic recrystallization occurs during FSW [15][16][17][18]. In all samples, while high heat resulted in the recrystallization of the grain structure of the nugget zones, plastic deformation resulted in a homogeneous structure.…”

In this study, CuZn37 plates were joined by using friction stir welding. Welding was performed at a rotational speed of 750 rpm and a welding speed of 20 mm min −1 , and at a rotational speed of 1000 rpm and welding speeds of 20, 40, 60 mm min −1. The welded samples were analyzed at the macro-microstructural level. Moreover, both hardness and fatigue tests were performed on samples. At the end of the macrostructural examination of the samples welded at the rotational speed of 1000 rpm and the welding speed of 20 mm min −1 , the formation of tunnel defects was observed. While the best fatigue life results at low strain rates were obtained in the samples joined at the rotational speed of 750 rpm and the welding speed of 20 mm min −1 , those at high strain rates were obtained in the samples joined at the rotational speed of 1000 rpm and the welding speed of 60 mm min −1 .

Material deterioration caused during service life led to the development of erosive/corrosive resistant materials. The present work focuses on characterization of an alloy, naval brass, developed by microwave hybrid heating method, which is a vital material used in ship building/ marine industry. Mechanism of melting of metals by microwave hybrid heating technique is presented in the article. Microstructural study reveals formation of alpha and beta phases, with negligible porosity. X-Ray Diffraction study reveals the presence of CuZn phase in the developed alloy. Further, tensile and microhardness characteristics of the cast alloy holds good with the properties that must be exhibited by the specified standard material.

“…In recent years, FSW of copper and it alloys (specially the CuZn or brass alloys) has been investigated by researchers [6][7][8][9][10][11][12][13][14][15][16]. For example, Heidarzadeh et al [6] have compared the FSW of single and double phase brass alloys. They reported that the presence of secondary phase in the double phase brass causes higher strength and lower elongation.…”

Nanoindentation test was employed to measure the actual hardness and yield strength of the stir zone in the friction stirwelded single-phase brass joints. For this aim, different joints were prepared according to an experimental matrix based on the central composite rotatable design. In this design matrix, the tool rotational speed, tool traverse speed, and tool axial force were the input parameters. The outputs were the hardness and yield strength of the joints. To measure the hardness and tensile strength of the joints, the nanoindentation test was employed. Moreover, electron back scattered diffraction and transmission electron microscopy techniques were used to study the microstructural features. The results showed that by decreasing rotational speed and axial force, and by increasing the traverse speed, the hardness and yield strength of the joints were increased. In other words, lower heat inputs caused higher strength in the joints. Finer grain sizes, larger grain average misorientation amounts, i.e., existence of more dislocations, and greater Taylor factors in the lower heat input joints revealed that the influence of grain boundaries, dislocations, and texture were the origins of better mechanical properties.
