Abstract Scope |
Tensile tests of Mg-Y and Mg-Ce single crystals at various temperature were carried
out to investigate alloying effects on activity of pyramidal <c+a> slips.
Both alloy single crystals were yielded by activation of {11-22}<11-23> second order
pyramidal slips at low alloy concentration. In Mg-Y alloy, {10-11}<11-23> first order
pyramidal slip appeared at high yttrium contents and the CRSS of the pyramidal slip increased.
The CRSS of second order pyramidal in Mg-Ce was lower than that of pure magnesium.
Effect of yttrium and cerium on the CRSS of pyramidal slips was discussed based on
dislocation mechanism of pyramidal slip. |
