| Definition of lower boundary in region of strength joints at high rate of strain of metals (1994) | |||||||||||||||
Abstract | |||||||||||||||
| Explosive weldability windows were determined by means of experiments to obtain bimetallic joints with strength not less than that of the weaker material. To construct the weldability window correctly the influence of factors not previously taken into account has been investigated. These factors are the dependence of the polytropic exponent of the explosion products on detonation velocity, the periphery distortions under casting of the plate and the influence of material strength on the plate collision geometry. Mathematical relations to calculate the lower boundary of the weldability window, the optimum residual pressure, the dimensions of the zone of periphery effects and the polytropic exponent have been developed. | |||||||||||||||
