Cryogenic Mechanical Properties of A5083-SUS304 Explosively Bonded Joint

Abstract

The development of high field conducting technique has created needs for new structual alloys and ensured joining methods. In this report, in order to examine the applicability of the explosively bonded joint for dissimilar materials to cryogenic machines, A5083P-SUS304L explosively bonded joint which had AllOOP, Ti and Ni layers as insert metals was prepared, and deformation and fracture behavior of its joint was investigated. The tensile test was carried out at 293K, 77K and 4.2K.
As the results, it was clarified that the deformation and fracture behavior of that joint was hardly affected by A1100P used for insert metal and that its strength was increased by restraint of deformation. Also it was recognized that the bond interface fracture was occurred in the region of lower temperature and harder restraint. But their ultimate tensile strength was twice as great as the offset stress of A1100P at least even at 4.2K.
