✦ Synopsis

The work hardening properties of a friction stir welded (FSWed) magnesium alloy were evaluated using two modified equations of hardening capacity and strain hardening exponent where the elastic deformation stage was excluded. Kocks–Mecking type plots were used to show different stages of strain hardening. The hardening capacity of the FSWed samples was observed to be about twice that of the base alloy, while the strain hardening exponent of the FSWed samples was nearly threefold higher than that of the base alloy.
