Correlation between the Microstructure and Forces Generated during Friction Stir Processing of AA5052

Abstract

The microstructure of friction stir processed AA5052 sheets is investigated using Scanning Electron Microscopy (SEM) and Orientation Imaging Microscopy. The correlation between the generated forces during processing and the microstructure is evaluated. Observations indicate that the finest microstructure are achieved when the plunging forces are at minimum.

Experimental investigation of underwater friction-stir welding of 5083 marine-grade aluminum alloy

“…The heat exerted on the samples during FSW and SFSW has a significant effect on the microstructure, microhardness, and tensile properties of the welded product. [19][20][21][22] The thermal histories presented in Figure 3 were used to view and compare the peak temperature reached when welding different samples, the cooling rate, and how long the temperature stayed above a reference point. The results presented in this section were used to examine the effect of different process parameters on the resulting microstructure and mechanical properties.…”

Friction stir processing of commercial AZ31 magnesium alloy

“…Accurate correlations are needed for successful modeling and process optimization. Most of the work that has been done in the field of friction stir processing focuses on aluminum alloys [2][3][4][5].…”

Prediction of Friction Stir Processed AZ31 Magnesium Alloy Micro-Hardness Using Artificial Neural Networks

“…FSP tool consists of: a shoulder which is responsible for generating frictional heat at surface, and a pin penetrating the sheet to stir the soften material. Several studies showed that FSP successfully modify the microstructure and consequently the properties of different alloys specially aluminum and magnesium [2][3][4][5][6][7]. Mishra et al [2] studied the effect of FSP on the superplastic behavior of several aluminum alloys, in their work they reported that significant grain refinement was achieved with FSP resulting in an enhancement in the superplastic behavior of the material.…”
