Optimization of Corrosion Behavior in Submerged Friction Stir Processed Magnesium AZ31B Alloy
Volume 2: Advanced Manufacturing, 2017In this research, friction stir processing of AZ31B magnesium alloy of 6 mm thickness was done in submerged conditions. The process parameters, i.e. tool pin profile (simple cylindrical, stepped cylindrical, stepped square), rotational speed ranging from 800 to 1200 rpm and traverse speed ranging from 0.5 to 1.5 mm/sec were optimized using the multi ...

Corrosion properties of low carbon steel prepared by submerged friction stir processing
Materials and Corrosion, 2018Submerged friction stir processing (SFSP), that is, the entire process was carried out underwater, was successfully conducted on low carbon steel. The microstructure, electrochemical corrosion, and salt fog corrosion properties of SFSP low carbon steel were investigated.

Normal and submerged friction stir processing (SFSP) were conducted to AZ91 magnesium alloy plates with 6mm in thickness, and influence of processing speed (ν) on microstructures and mechanical properties of the experimental materials was investigated. The results revealed that fine and equiaxed grains were observed in the stirred zone (SZ).

Friction stir welding (FSW) is a solid-state welding process which is used to join high-strength aircraft aluminum alloys and other metallic alloys which are difficult to weld by conventional fusion welding. In this paper, AA6063-O alloy of 6mm thickness was taken and friction stir welded under the water in order to improve the joint properties.

High‐Strain‐Rate Superplasticity in Mg–Y–Nd Alloy Prepared by Submerged Friction Stir Processing
Advanced Engineering Materials, 2015Superplastic tensile behavior of Mg–Y–Nd alloy prepared by submerged friction stir processing (SFSP) is investigated. Microstructure of the SFSP alloy is mainly composed of fine‐grained magnesium grains (≈1.3 µm) and homogeneously distributed second‐phase particles. Elongations are all above 500% within a wide high‐temperature range of 708–758 K at 1 ×
