Using the Wavelet Transform for Mechanical Activation and Thermal Explosion of a Ti-Ni Mixture

摘要

The paper represents the experimental study of a titanium and nickel powder mixture subjected to mechanical activation (MA), followed by the self-propagating high-temperature synthesis (SHS) in the mode of thermal explosion with the formation of a synthesized product. This system is investigated as a self-consistent system. The formation of agglomerates during MA, the temperature characteristics of thermal explosion, and the composition of the synthesized product are studied. The MA times for obtaining the main events in the system, the optimal MA times for obtaining the compositions of a certain phase, and the corrected limiting values for the operation of the system are found. The inheritance of the behavior of each subsystem is revealed in the further steps to obtain a synthesized product.
