Аннотация
We explored the influence of mechanical activation (MA), thermovacuum degassing (TVD), and ambient pressure on burning velocity and sample shrinkage/elongation for SHS reactions in cylindrical Ti + 0.5C powder compacts. Thermovacuum degassing of Ti + 0.5C mixtures was found to increase the burning velocity (2-fold) and sample shrinkage. Mechanical alloying decreased the burning velocity and gave large (3-fold) sample elongation. The results can be readily rationalized in terms of conduction-convection combustion theory.
