抄録
The effect of θ precipitates and deformation at elevated temperatures on the shear band formation has been investigated in rolled single crystals of an Al-2%Cu alloy based on observations of slip bands and dislocation structures. Irrespective of heat treatments to give either a nominal solid solution or θ precipitates, shear bands were not formed in (011)[\bar100] crystals but in (211)[\bar111] crystals during rolling at room temperature. Increase in the temperature up to 473 K resulted in rather homogeneous slip and developed no shear bands even in the (211)[\bar111] crystals. A simple correlation between the shear band formation and dislocation structures was found; the shear bands occurred in the crystals in which aligned micro-bands (layered dislocation walls) evolved.
