In this study, corrosion behavior of Ti-6Al-4V titanium alloy joint by friction stir welding with a rotational speed of 375 rpm and a travel speed of 100 mm/min was investigated. The welding procedure was carried out under β-transus temperature that was consisted of equiaxed grains in the stir zone. The corrosion behavior of the welded joint was investigated in 3.5% NaCl solution at temperature...
abstract – aluminium 7075- t651 alloys are widely used in the production of light weight structures requiring a high strength to weight ratio and high corrosion resistance. the effect of processing parameters on fatigue life of 7075- t651 aluminium joints produced by friction stir welding was investigated in the present study. welding samples were made by employing rotating tool speed of 770, 9...
in this research, surface composite layers containing nano sized tib2, al2o3-tib2, zro2 and cnt particles have been fabricated on aluminum alloy substrates by friction stir processing. the effects of different processing variables such as number of passes and strengthening particle distribution, hardness, and wear properties of surface nanocomposite layers have been evaluated by electron micros...
In present study, the effect of heat treatment after friction stir welding dissimilar welds T6-7075 and T4-2024 aluminum alloys were investigated. Friction stir welding was performed at a constant rotation speed of 1140 rpm and welding speed 32 mm/min. After welding samples are taken under various heat treatment processes at different aging temperature and time period. Microstructural observati...
Friction Stir Welding is one of the solid-state processes and today it has been used to join different types of materials. Friction stir welding does not have many problems and limitations due to melting and solidification of weld metal and by controlling its variables, the microstructure and desired mechanical properties can be achieved at the joint. Recently, in most industrial areas, due t...
