Mechanical processing of reactive laminates

摘要

A method of producing a reactive powder includes providing a bulk structure of reactive material comprising a first reactant and a second reactant, the bulk structure having a preselected average spacing between the first and the second reactants; and mechanically processing the bulk structure of reactive material to produce a plurality of particles from the bulk structure such that each of the plurality of particles comprises the first and second reactants having an average spacing that is substantially equal to the preselected average spacing of the bulk structure of reactive material. The first and second materials of the plurality of particles react with each other in an exothermic reaction upon being exposed to a threshold energy to initiate the exothermic reaction and remain substantially stable without reacting with each other prior to being exposed to the threshold energy.

1. A method of producing a reactive powder, comprising:
providing a bulk structure of reactive material comprising a first reactant and a second reactant, said bulk structure having a preselected average spacing between said first and said second reactants; and mechanically processing said bulk structure of reactive material to produce a plurality of particles from said bulk structure such that each of said plurality of particles comprises said first and second reactants having an average spacing that is substantially equal to said preselected average spacing of said bulk structure of reactive material and separating said plurality of particles according to size to provide a plurality of separated particles, wherein said first and second reactants of said plurality of particles react with each other in an exothermic reaction upon being exposed to a threshold energy to initiate said exothermic reaction and remain substantially stable without reacting with each other prior to being exposed to said threshold energy.
