N2 - The evolution of the microstructure and mechanical properties (for example, microhardness) of biodegradable alloy Mg-0.8 wt % Ca after multi-pass rolling in grooved rollers at different accumulated strain values e = 0.4, 0.9, 2.0 was investigated. As a result of multi-pass rolling under cumulative deformation e = 2.0, the recrystallized structure with average grain size of 1.4 μm and ultrafine grain volume ratio of up to 35% were formed in the alloy. It was proved that the absence of alloy strengthening after rolling was associated with the fact that the strengthening due to grain size refinement was compensated by annealing, as a result of dynamic recovery. This also resulted in further redistribution of the phase composition with decreasing volume ratio and Mg2Ca particle dispersion.
