“…Similar higher stress exponent values have been reported for creep in Mg dispersed with 0.05% MgO [15] which inhibited diffusional creep. Also, stress exponent values in the range 916 have been observed in the higher stress range during creep of magnesium strengthened with high value fractions of yttria dispersoids [16,17].…”

The hot deformation behavior of extruded Mg/nano-Al2O3 composite has been studied in the temperature and strain rate ranges of 300-500°C and 0.0003-10 s-1. In the lower strain rate regime (<0.1 s-1), the apparent activation energy evaluated is much higher than that for lattice self-diffusion. At higher strain rates, the behavior of the composite is similar to that of the matrix material and is controlled by grain boundary self diffusion. The prior particle boundaries in the composite, which are decorated by the nano-alumina particles, are stable and only kink under compression parallel to the extrusion direction.

“…This texture reduction is due to the presence of HA particles, which stimulate the recrystallization of randomly-oriented grains by particle stimulation nucleation (PSN) mechanism. In the research performed by Garcés et al [52], the texture of Mg matrix was also vanished by reinforcement particles. In addition, Campo et al [24] found that the reinforcement particles tend to prevent the appearance of the texture produced by the extrusion process.…”

“…It is notable that in most of the cases reported before, grain boundary strengthening effect has been the major source of strengthening in the composites prepared by the powder metallurgy process, due to the small matrix grain size [31,32]. In the present study, however, the monolithic and composite materials had similar grain sizes, as shown in Fig.…”
