Abstract Aluminum alloy 2219-T6 was friction stir processed using a novel submerged processing technique to facilitate cooling. Processing was conducted at a constant tool traverse speed of 200 mm/min and spindle rotation speeds in the range from 600 to 800 rpm. The microstructural characteristics of the base metal and processed zone, including grain

Submerged Friction Stir Processing of AZ31 Magnesium Alloy
Materials & Design, 2013Abstract Friction stir processing (FSP) has recently emerged as a microstructural modification technique. FSP can be used to effectively produce ultrafine and homogenous grain structure. The process is found to be very sensitive to thermal histories.

Thermal history analysis of friction stir processed and submerged friction stir processed aluminum
Materials Science and Engineering: A, 2007Abstract In this research, equations are developed to model the rate of heat input from different geometries of friction stir processing (FSP) tools. The model is then compared with actual heat input obtained from embedded thermocouples within the stirred region.

Abstract In this research, the combined effect of pre-rolling and submerged friction stir processing (SFSP) on the microstructure, hardness, and tensile behavior of commercially pure copper were evaluated. Several voids and cavities were observed in the stirred zone of 0 %–400, 60 %–400, 60 %–600, and 0 %–800 samples, and the defect-free copper could

Abstract This paper reports on the influence of the pin profile towards the microstructure and the mechanical properties of the underwater friction stir processed dissimilar (SFSP) AA6082/AA8011 joint. The friction stir processed (processed) dissimilar joints were initially produced through the friction stir welding technique. The SFSP joint produced

Structural refinement in austenitic stainless steel by submerged friction stir processing
Materials Chemistry and Physics, 2017Abstract In the current study, surface modification of austenitic stainless steel, SS316L, was done using friction stir processing. The strain rates during processing were varied over a wide range by using two different tool rotational speeds of 388 rpm and 1800 rpm. The processing was done at two different conditions of: (i) ambient cooling and (ii)

Abstract This research demonstrates the use of submerged friction stir processing (SFSP) as an alternative and improved method for creating ultra-fine-grained bulk materials through severe plastic deformation. SFSP is compared with friction stir processing (FSP) done in air, through the use of thermocouples and transmission electron microscopy ...
