Abstract
Monolithic metal bodies (e.g., hard aluminum alloys) comprising a continuous microcavity contained within the body are disclosed. The ratio of the cross-sectional area of the metal body to the cross-sectional area of the microcavity may be not greater than 10. The produced metal bodies may be used in structural applications (e.g., aerospace vehicles) to monitor or test the integrity of the metal body.
