Notes:
High temperature deformation behavior of AZ31 and AZ91 magnesium alloys wasexamined by compression tests over a wide strain rate range from 10–3 to 103 s–1 with emphasis onthe behavior at high strain rates. The dominant deformation mechanism in the low strain raterange below 10–1 s–1 was suggested to be climb-controlled dislocation creep. On the other hand,experimental results indicated that the deformation at a high strain rate of ~103 s–1 proceeds byconventional plastic flow of dislocation glide and twinning even at elevated temperatures. Thesolid-solution strengthening was operative for high temperature deformation at ~103 s–1
