“…In addition, stability against dislocation motion is caused by the high hardness of these ceramic particles, giving rise to higher hardness in the nugget zone. This is also in good agreement with the report by Fallahi et al (2017).…”

Prior to friction stir welding (FSW), silicon carbide (SiC) nanopowders were placed inside the groove on the adjacent side of magnesium sheet. In order to make a good distribution of these nanoparticles, first, friction stir processing (FSP) with a pinless tool was conducted on this side. Second, using a frustum pin tool, a combination of two travel speeds (25 and 35 mm/min) and three rotation speeds (550, 600 and 650 rpm) were employed to obtain the optimal conditions for FSW of AZ31 magnesium alloy to 6061 aluminum alloy. The joint fabricated at 35 mm/min and 650 rpm, exhibited improvement of 28% in tensile strength and enhancement about three times in elongation, compared with the joint without nanoparticles. SiC nanoparticles had an effective role on the grain refining of the stirred zone and improving the microstructural characteristics of the banded structure zone. Due to the decreased grain size and the presence of ceramic nanoparticles (SiC) with high value of hardness, the hardness level of the reinforced samples was greater than that of the non-reinforced samples. Fracture of the non-reinforced sample was completely brittle, while in the reinforced samples, fracture features changed to the ductile mode.

“…Современные исследователи [1][2][3][4][5][6] демонстрируют высокий интерес к процессу сварки разнородных металлов методом сварки трением с перемешиванием (СТП), который в настоящее время находит всё более широкое применение в промышленности. Данный метод сварки позволяет осуществлять соединение металлов без их расплавления, в твёрдой фазе, и часто без использования дополнительных проставок, хотя их наличие также является темой исследований [5,7]. Рассматривая сварку других систем, таких как медь с алюминиевым сплавом, алюминиевый сплав с нержавеющей сталью, алюминиевый сплав с титановым сплавом, стоит выделить исследование [8].…”

Рассмотрена схема образования стыкового соединения алюминиевых сплавов со сталью со смещением инструмента. Проведен анализ качества и структуры швов, полученных согласно данной схеме. Исследован микрошлиф полученного образца сварного шва алюминиевого сплава АМГ6 с нержавеющей сталью 12Х18Н10Т толщиной 2 мм при частоте вращения инструмента 500 об/мин и подаче 50 мм/мин со смещением инструмента на 0,2 мм в стальную заготовку. В ядре шва наблюдается взаимное проникновение металлов на глубину до 3,2 мм и стальные включения в алюминиевом сплаве размером до 0,3 мм. Ключевые слова: сварка трением с перемешиванием, фрикционная сварка, сварка разнородных металлов, алюминиевые сплавы, нержавеющая сталь, структура сварного шва.

“…In many constructions, using hybrid elements is expected to be one of the best ways for weight reduction and as a consequence, environmental protection and energy preserving [2,3]. For this purpose, bimetal joints with a lightweight component and steel are taking attention because of particular features of steel metals and lightweight material [4]. Because of the following explanations, steel/Mg joints come to be increasingly attractive compared to other dissimilar joints.…”

Dissimilar transient liquid phase (TLP) bonding of AZ91C magnesium alloy to 316L stainless steel was carried out using a pure copper filler metal. The bonding process was conducted in two stages where TLP bonding of 316L to Cu interlayer was first performed and then followed by bonding AZ91C to the other side of the copper interlayer. It was indicated that the temperature rise enhanced the inter-diffusion of elements at the AZ91C/Cu interface and encouraged the formation of hard intermetallic Mg2Cu compound. Refinement of Cu grains was observed and attributed to the induced strain from the fixture. This phenomenon assisted the enhancement of mechanical properties of the joints. By increasing the temperature from 495 to 530 • C, the shear strength revealed an upsurge of more than 20 %. The presence of Mg2Cu was detected as the main contributor to the increased shear strength and microhardness at elevated temperatures.
