Abstract

The glide dislocation-precipitate interaction in under-aged alloy is investigated by microscopy and low-temperature deformation techniques. Slip-line features of room temperature deformed samples were observed by optical microscopy. From tensile tests at various temperatures the variation of flow stress with $T^{2/3}$ was established. Comparing the present results with those obtained on the peak-hardened condition of the same alloy it is concluded that moving dialoation shear through the small rod-shaped germanium precipitates.
