Abstract
The development of several defects such as hydrogen embrittlement, solidification cracks, porosity, blowholes, and undesirable metallurgical changes that occur in fusion welding can be elegantly mitigated by lowering the peak temperature in underwater friction stir welding. Therefore, this article delves into the effect of tool rotational speed on mechanical properties as well as the microstructural evolution of underwater friction stir welded AA1100-H18. Mechanical properties such as Rockwell hardness, tensile test and impact test as well as microstructural analysis through optical micrograph and scanning electron microscope were analyzed. The results showed that grains are refined and properties get enhanced at optimum rotational speed.
期刊介绍：
Russian Journal of Non-Ferrous Metals is a journal the main goal of which is to achieve new knowledge in the following topics: extraction metallurgy, hydro- and pirometallurgy, casting, plastic deformation, metallography and heat treatment, powder metallurgy and composites, self-propagating high-temperature synthesis, surface engineering and advanced protected coatings, environments, and energy capacity in non-ferrous metallurgy.
