The formation of thermal stresses in thermal explosion synthesis products taking into account changes in phase composition for Ni-Al mixture
In the work, the method of assessing stresses and deformations in the process of the synthesis of the intermetallide in the thermal explosion mode of the Ni-Al powder mixture in the cylindrical reactor is proposed. The task is reduced to the problem described in the literature about the stress-strain state of the coating cylinder. To estimate stresses in the sample, the first approximation uses well-known problems of thermoplasticity, including those having analytical solutions. Each calculation provides complete information on the distribution of the concentrations of the elements of compounds and phases, as well as the formation of stresses and deformations in various layers of the sample.
