NiAl bronze (NAB) alloy is prepared by using friction stir processing (FSP) technique at a tool rotation rate of 1200 rpm and a traverse speed of 150 mm/min. A post heat treatment is performed at the temperature of 675 °C. The effect of heat treatment on the microstructure and microhardness is studied. The results show that the microstructure of the FSP NAB alloy consists of high density disloc...
the friction stir process (fsp) is a solid state process, which has been used to insert reinforcing particles into the structure of a material to create a composite with improved properties. magnesium is a light structural metal that is increasingly used in the aerospace and automobile industries. in this research, sic nanoparticles were added to az31 alloy using fsp in two overlaps of 100% and...
A commercial 2024 aluminum alloy was heat treated at 280 °C for 48 h and then slow cooled in a furnace to obtain minimum hardness. This material friction stir processed (FSP) using three sets of processing conditions. To study the effect on microstructure high temperature mechanical properties, materials were tested tension an initial strain rate 10−2 s−1 range 200 450 °C. Processing severity s...
