Abstract
The burning rate and limits of ribbons rolled from mixtures of titanium with boron were determined as a function of the concentration of boron. The combustion of single ribbons near the lower limit is unsteady and has a two-zone structure across the width of the ribbons, due to the difference in burning and cooling rates between the edges of the ribbons and its middle. With increasing boron concentration in the mixture, the combustion becomes steady-state and the front becomes more even. Maximum burning rate of the ribbons is achieved at a boron concentration of 21-25% in the mixture.
