A STUDY OF EXPLOSIVE FORMING SELECTED REFRACTORY METALS
Abstract
A study was made to determine the explosive forming characteristics of Mo 0.5% Ti alloy and tungsten. The study included an investigation to optimize the strain rate condition up to and including a forming temperature of 1000 F. A brief analysis was also made to determine the prime factor to be considered in the choice of a transmission media. For 40% dynamite, the Mo-1/2 Ti displayed a maximum strain rate of approximately 18 in./in./sec with a resulting elongation of 9 per cent. The strain rates for W, using both RDX and 40% dynamite were essentially the same as those for the Mo-1/2 Ti. The maximum achievable elongation for W varied from 6% for 40% dynamite to 9% for RDX. Although a somewhat great elongation could be obtained for both Mo-1/2 Ti and W using RDX, results of forming tests indicated that optimum conditions could be better approached through the use of lower detonation 40% dynamite.
