Paper Title:
Structural Stability of Composite Materials Prepared by Explosion Welding after their Heat Treatment
  Abstract

As is well known, the explosion welding is considered for a specific type of cold pressure welding. Welded joints fabricated by this technology show a typical undulated boundary, which characterises both, the welding process and bond quality. This technology allows to weld a relatively wide assortment of combinations of various metals and their alloys [1,2]. This contribution presents the technological procedure for preparation of composite materials based on three metals (trimetals) by use of industrial explosive Semtex S. It concerns the trimetals as structural carbon steel-Cu-Al and structural carbon steel-Ti-Al. For the anodes and cathodes of electrolysers, used for manufacture of aluminium, mostly bimetals were used up to now, as for example the structural carbon steel – Al. However, the mentioned trimetals exert certain priorities over bimetals, regarding mainly the structural stability at elevated temperatures. This also results in higher reliability at breakdown situations and also in longer life of weldments proper. The mentioned trimetals were prepared at Explosia Inc., Research Institute of Industrial Chemistry Pardubice-Semtín. The bond quality was assessed by optical microscopy, microhardness measurement across the bond boundary and also by X-ray microanalysis.
