摘要：

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 nun 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).
