Özet

© 2021 Trans Tech Publications Ltd, Switzerland.The influence of grain refinement by high pressure torsion (HPT) on microstructure of the Mg-1%Ca alloy was investigated by scanning and transmission electron microscopy. To The microhardness measurements and tensile tests of small samples were used to determine the mechanical properties of UFG samples. It was found that a uniform structure with an average grain size of 210 nm processed by HPT lead to high microhardness equal to 100 HV. Investigations of thermal stability demonstrated that additional heat treatment of the UFG samples at 250 oC provides good combination of high strength of 245 MPa and ductility of 4%.
