Computerized Tomography of High Explosives
Computerized tomography (CT) techniques are being investigated to improve the current manufacturing process flow of high explosives (HE). In order to revise the manufacturing process flow, it must be demonstrated that CT can provide information comparable to the techniques currently used: 1) shadow graphs, to determine gross outer dimensions; 2) radiography, to detect cracks, voids, and foreign inclusions; 3) dye penetrant, to identify surface cracks; 4) a wet/dry bulk-density measurement technique; and 5) destructive core sampling for exhaustive density measurements.
