Fsw Parameters

The aim of this research was to investigate the effect of friction stir welding (FSW) parameters on microstructure and mechanical properties of Sc-modified AA2519 extrusion joints. The workpiece was welded by FSW in non-heat-treated condition with seven different sets of welding parameters. For each obtained joint macrostructure and microstructure observations were performed. Mechanical properties of joints were investigated using tensile test together with localization of fracture location. Joint efficiencies were established by comparing measured joints tensile strength to the value for base material. The obtained results show that investigated FSW joints of Sc-modified AA2519 in the non-heat-treated condition have joint efficiency within the range 87–95%. In the joints obtained with the lowest ratio of the tool rotation speed to the tool traverse speed, the occurrence of imperfections (voids) localized in the stir zone was reported. Three selected samples were subjected to further investigations consisting microhardness distribution and scanning electron microscopy fractography analysis. As the result of dynamic recrystallization, the microhardness of the base material value of 86 HV0.1 increased to about 110–125 HV0.1 in the stir zone depending on the used welding parameters. Due to lack of the strengthening phase and low strain hardening of used alloy the lack of a significantly softened zone was reported by both microhardness analysis and investigation of the fractured samples.

The slag bath accelerated formation technological processes in the "solid" start of mono-and bifilar process schemes are worked out. The melted electroslag steel 5ХНМ (5HNM) and 34ХН1М (34HN1M) properties satisfy to the requirements that apply to the open wrought metal smelting mechanical properties. It is found that an effective way to enhance productivity is the electroslag processes exothermic flux (slag, ferroalloys, and aluminum powder in amounts sufficient to exothermic reactions) use. It is experimentally proved that an electrically conductive layer exothermic flux presence allows electroslag process, both in mono and bifilar schemes in "solid" start. The 34ХН1М (34HN1M) steel in non-heat treated condition tend to hairline cracks formation. The heat treatment provides the required mechanical properties and the hairline cracks absence in electroslag molten metal.
