Limiting Pressure

A high energy rate metal forming concept is described that uses energy from a high velocity free piston impacting on a liquid. The piston is driven by compressed air. The characteristics of the energy transfer and the pressure buildup are analyzed for a limiting case. A basic typical system design is presented. Schematic diagrams and curves illustrating limiting pressure rise and other characteristics of a typical system are presented.

Rapidly Solidified

The aim of the present work is to produce new types of solid nanomaterials for different purposes (coatings, fillers, foams, bulk pieces, etc.). Technologies such as RS Al flake production, high energy mechanical milling and high energy rate forming technology (HERF) for compacting are used. The products are analyzed mainly by XRD, SEM and TEM methods. It was shown that the new-type of RS Al “flake” material is suitable not only for pigments but also for powder metallurgical purposes, i.e. Al based nanocomposites. By choosing suitable parameters for mechanical alloying with the Fritsch Planetary mill 4, very fine, alloyed and composited nanostructures can be produced (Al-4.5w%Cu- 10w%Al2O3, Al-15w%Pb) Dynamic compaction (HERF) using explosive techniques seems to offer a good way for the compaction of Al (metal) matrix nanostructured composites.
