ABSTRACT

N d at higher temperatures than in pure M g . So, in the alloy with N d , twins formed up to

temperature 350°C as compared with only 250°C for pure M g . The evident migration of

the grain boundaries and formation of the serrated grain boundaries, which were typical of

hot deformation of pure M g , were not observed in the alloy with N d even at 400°C.

Meanwhile , in pure M g the serrated grain boundaries and migration of the grain boundaries
