Abstract

In the present investigation, the peak temperatures during friction stir processing (FSP) of cast A319 Al alloy were
measured using thermal imaging technique. The FSP was conducted using different tool rotational speeds, tool traverse
speeds and number of passes. The influence of the aforementioned FSP process parameters on the peak temperature
were investigated. Moreover, the analysis of variance (ANOVA) statistical approach was used to evaluate the
significance of these parameters. The results revealed that increasing the tool rotational speed and/or the number of
passes increases the peak temperature. However, increasing the traverse speed reduces the peak temperature. The
maximum-recorded peak temperature was about 524 oC, which is about 85.76% of the melting temperature of A319
alloy
