Abstract
Static and dynamic powder compaction and forming processes have been used for fabricating engineering components from powders of metals, ceramics, polymers and composite materials. The principal advantages of powder-metallurgy processing are its versatility for making parts in a wide range of sizes close to the final dimensions and finish, with little or no subsequent machining, as well as that an increased homogeneity of resulting metallurgical structure is secured. In the present investigation the explosive-compaction technique has been employed for producing cylindrical rods of copper/graphite powders using a steel container. In this paper, experimental observations of fracture-damage developments and microstructural changes which occur during the direct explosive-compaction process are outlined. The microhardness distribution was measured and damage “regions” are indicated. An attempt was made to explain qualitatively some modes of fracture in terms of stress wave-front developments.
