摘要： A syntactic metal foam composite that is substantially fully dense except for syntactic porosity is formed from a mixture of ceramic microballoons and matrix forming metal. The ceramic microballoons have a uniaxial crush strength and a much higher omniaxial crush strength. The mixture is continuously constrained while it is consolidated. The constraining force is less than the omniaxial crush strength. The substantially fully dense syntactic metal foam composite is then constrained and deformation worked at a substantially constant volume. The deformation working is typically performed at a yield strength that is adjusted by way of selecting a working temperature at which the yield strength is approximately less than the omniaxial crush strength of the included ceramic microballoons. This deformation causes at least work hardening and grain refinement in the matrix metal.

摘要： Apparatus and method for working of a workpiece use the expansion of water in a container during the freezing process to drive a piston against a workpiece that is positioned to at least partially overlie a cross-sectional area of a hollow interior of the container. Use of a piston with a tapered working end focuses the resulting force against a small area of the workpiece in order to produce a bend in the workpiece at the point of application. In environments where conventional bending tools are not available, the apparatus can be used to perform bending or other operations on workpieces of varying materials.
