The land method was used to study the structure of Al single crystals (99.9997% pure) grown from the melt, the thermal stability and the character of changes in different subgrain structures during work hardening. The method has proved to permit observation of slip development both in the early strain region (where occurs “levelling” of the structure of the bulk under strain), and during concert dislocation movement in specific slip planes up to large strains at 4.2°K.
