In this paper, the effects of two parameters named width of the roller and exerted force on it in direct and indirect rolling, on residual stresses in Friction Stir Welding (FSW) process of SU304 steel have been studied. ...

The effect of pre-compaction on mechanical properties of Mg/SiC nanocomposites prepared through dynamic compaction was investigated. The dynamic compactions were carried out at two different loading rates using Drop ...

In this article, the friction stir welding of dissimilar AA6061-T6/AA7075-T6 aluminum alloys was studied experimentally. The joining process was implemented with and without the addition of the TiO2 nanoparticles. To ...

In the current study, magnesium-matrix AZ31/ 1.5 vol.% (TiO2)p nanocomposites manufactured using stir casting underwent extrusion process. The as-cast ingots were extruded, then processed by multidirectional forging (MDF) ...

Friction stir processing (FSP) in different pass number, accordingly one and four, was performed to AZ31 magnesium alloy. Optical and scanning electron microscopy (SEM) were used to investigate the effect of FSP and its pass ...

Continuous investigation and measurement of pore water pressure and arching depression play an important role in detecting the occurrence of hydraulic failure in earth dams. Increasing the pore water pressure during the ...
