Crack prevention in shock compaction of powders
conference paper
The occurrence of macro-cracks in compacts fabricated by shock compaction of powders is a severe problem preventing this consolidaúon technique from commercial applications. In this paper the sources of important failure types that typically occur in tlre cylindrical configuration i.e. radial, transverse, and spiral cracks and the Mach stem a¡e described. Subsequently, solutions for thei¡ prevention are given supported by experimental results and/or computer simulations. Some conflicting requirements for obtaining bonded crack-free compacts are discussed.
