Abstract

We propose a stationary shoulder friction stir process (SSFSP) to produce a smooth surface finish. The use of a stationary shoulder tool contributes to reducing the heat input during friction stir processing (FSP). Hence, a stationary shoulder tool is advantageous for FSP in heat sensitive alloys like magnesium. The present short communication investigates the surface finish of AZ31B magnesium alloy processed by SSFSP without using additional cooling. Surface analysis of the processed region was carried out by 2D and 3D surface mapping using digital microscopy. The surface mapping indicated that there was very little flash generation on the processed zone, while 3D mapping quantified the surface roughness in the longitudinal as well as transverse directions of the processing zone.
