چکیده

در جوشکاری توپودری، ریزساختار و خواص مکانیکی اتصال آلیاژ فولاد 304 AISI توسط نانوصفحات اکسید گرافن (GO) و اکسید گرافن احیا شده (RGO) بررسی شد. در این پژوهش ریزساختار خط ‌جوش توسط روش‌های متالوگرافی و میکروسکوپ الکترونی روبشی گسیل میدانی، فازهای تشکیل شده توسط روش پراش پرتوی ایکس و تغییرات آلوتروپی کربن توسط آزمون طیف‌سنجی رامان ارزیابی شده است. اکسید گرافن با استفاده از روش هامر اصلاح شده سنتز شده و با استفاده از  هیدرازین احیا شد. بر این اساس، خمیر اکسید گرافن و اکسید گرافن احیا شده در غلظت‌های مختلف 1 ، 3 و 10 میلی‌گرم بر میلی‌لیتر برای پرکردن شکاف جوش استفاده شده است. نتایج نشان داد که با افزایش غلظت اکسید گرافن احیا شده تا 10 میلی‌گرم بر میلی‌لیتر، استحکام کششی و سختی جوشکاری به‌ترتیب تا 23 و 43 درصد بهبود می‌یابد. مکانیزم افزایش خواص مکانیکی را می‌توان احتمالاً به ایجاد ممانعت نانوصفحات اکسید گرافن احیا شده در برابر رشد دانه و درنتیجه ریز شدن اندازه دانه آلیاژ خط‌ جوش در حین فرایند انجماد حوضچه جوش متناسب دانست.

چکیده [English]

In this research, the effect of graphene oxide (GO) and reduced graphene oxide (RGO) nanosheets on the mechanical and microstructural properties of AISI 304 stainless steel welded joints produced by the flux-cored arc welding (FCAW) method was investigated. Light microscope, field emission scanning electron microscope (FE-SEM) equipped with energy-dispersive X-ray spectroscopy (EDS), X-ray diffraction analysis (XRD), Raman spectroscopy, and tensile strength test were used to characterize the samples. GO was synthesized by modified Hummers’ method and reduced by hydrazine. Accordingly, the pastes of GO and RGO in different concentrations of 1, 3, and 10 mg/ml were applied in the groove. The results demonstrated that increasing the RGO concentration up to 10 mg/ml improves the tensile strength and hardness values of welded joints up to 23% and 43%, respectively. It seems that RGO nanosheets have a significant effect on the mechanical properties of the welded joints by pinning of dislocations.
