Effect of Deformation Speed on Stress Corrosion and Fracture Toughness of Extruded Mg10Dy and Mg10Dy1Nd Using C-Ring Tests
The influence of the deformation speed in C-ring tests in Ringer's solution on crack initiation and propagation of extruded Mg10Dy and Mg10Dy1Nd is investigated. Deformation speeds varying from 2 to 0.012 mm/min allow corrosion times from a few minutes to hours. Both the crack initiation force (higher for Mg10Dy1Nd) and displacement (higher for Mg10Dy) increase with decreasing deformation speed up
