Features of Uniaxial and Biaxial Deformation of the Contact Boundary of Metals during Explosion Welding

Resumo

X-ray diffraction and scanning electron microscopy are used to study the nature of deformation of the contact boundary (weld seam) between dissimilar metals (Cu–Ti and Cu–Al) formed during explosion welding. Under biaxial dynamic loading, a significant plastic deformation of the contact zone and its heating up to higher temperatures are shown to occur. This is confirmed by the formation of intermetallic compounds in the weld seam. The level of plastic deformation of the weld zone can be estimated on the basis of the crystallization temperature of intermetallic compounds.
