This study by Abhishek Tripath et al. investigates the friction stir processing (FSP) of AZ31 magnesium alloy in different cooling environments (air, liquid nitrogen, and water), both experimentally and numerically.

Microstructure and Grain Refinement:

During the process, different cooling environments caused the grain size in the mixing zone to refine to varying degrees.

In the water environment, the grain size, which was initially 48 µm, was refined to 3 µm.

Macrostructure and Mixing Zone Sizes:

Significant differences were observed in the mixing zone sizes and temperature profiles, depending on the cooling environment.

Finite Element Analysis:

The numerical analysis of FSP effectively reflected the experimental observations regarding the mixing zone sizes and temperature profiles.

This study examines the effects of different cooling environments on FSP and reveals changes in both micro and macro structural properties of the AZ31 magnesium alloy.
