Abstract

TEM observations of dislocations and faults in an as-grown Al-Pd-Mn single crystal show that dislocation movements have occurred by pure climb in mirror planes. A comparison with creep properties of h.c.p. metals along their c-axis indicates that pure climb is a realistic deformation mode when glide is inhibited at high temperature.
