  The world first samples 0f Ti+SS and Nb+SS joints were manufactured by an
explosion welding technology demonstrating a high mechanic properties and leak
absence at 4.6 x 10^{-9} atm-cc/sec. Residual stresses in bimetallic joints
resulting from explosion welding measured by neutron diffraction method are
quite high (~1000 MPa). Thermal tempering of explosion welded Ti+SS and Nb+SS
specimens leads to complete relaxation of internal stresses in Ti,Nb and
Stainless steel and makes the transition elements quite serviceable.
