In a composite produced from a pseudoalloy by thermomechanical processing the density of microcracks does not grow with decreasing mean layer thickness. The anisotropy of the ADIF indicates that the directions of climb of edge dislocations and of slip of screw dislocations in the MCM are not equivalent. This circumstance must be taken into account when designing parts which are to be made of such materials, because the mechanical properties of sandwich-type composites are linked directly with the density and distribution of dislocations. At h<0.35 μm the boundaries of the layers of the MCM investigated constitute effective obstacles to dislocation motion. To obtain a composite material of high crystal structure defect density (and hence of increased ultimate strength), it is therefore necessary to reduce to a minimum the layer thickness. Thermal activation and cyclic loading at a cycle stress corresponding to the fatigue limit of the material lead to breakaway of dislocations. This enables loading conditions to be chosen under which recovery of the material can take place during cyclic deformation.
