The use of a line explosive charge in the expansion of water-filled brass tubes is investigated, both on a small experimental scale and on a large industrial scale. Results are presented showing how the radial velocity of deforming tubes and the distribution of hoop and axial strain in the deformed product are related. Metallurgical and some other aspects of the process are discussed.
