INVESTIGATION OF RECRYSTALLIZATION IN AN ALLOY OF THE MG-Y-LA-ZR SYSTEM

Magnesium alloys are a light material and for this reason they are of interest for technologies where the weight of structures should be dec reased to a minimum. Deformable magnesium alloys have very high streng th characteristics. The mechanical properties of deformable magnesium alloys are determined by the structural processes occurring in cold-ha rdening or its removal. One such process is recrystallization. The lit erature contains little data on recrystallization of magnesium alloys containing yttrium, although yttrium is an effective strengthening age nt for magnesium. The present work is devoted to the special features of recrystallization of a magnesium alloy of the Mg - La - Zr system c aused by introduction of yttrium into it.
