Refrigerators form two directions fronts of crystallization - axial and radial; two passers and two parallel, which meet also, interact in volume of samples. The arising structure of castings and her features is studied. Defects of structure of castings at the different directions of fronts are revealed, ways of fight against them are considered. Parameters of processes which allow to operate the sizes of a time and porosity of samples of gazars are considered and determined and to completely block emergence of defective zones and a time of merge. Level of cohesive strength of borders inclusion matrix in a wide interval of temperatures and speeds of deformation is studied, the analysis of the mechanism of transformation of borders inclusion matrix is carried out under different conditions of loading. Regularities educations of microcracks along interphase borders inclusion matrix in the conditions of contact interaction of different types of inclusions and a matrix are got at the different modes of plastic deformation after the previous laser processing or high-temperature annealing. Formation of structure of thin tapes from Pb-Sa-Sn alloy for the electrochemical accumulators received by way of continuous rolling is investigated. Results of researches have allowed improving technology of extra oven processing and also to specify parameters of the modes of deformation and thermal influences for the purpose of the guaranteed increase in technological.
