Stress States

Brazing of cemented carbides to steel bodies gives rise to the development of complex stress states and distortions which influence the fatigue behaviour of the parts. It is quite important to estimate the residual stresses with numerical methods whose agreement is to be guaranteed with experimental characterization of the brazed parts. In this work FEM simulations and X-ray as well as neutron stress analysis were used to examine the residual stresses of brazed samples. Joints with different geometries and dimensions made of cemented carbide and different steels showing different phase transformation behaviours were investigated.

Aiming at the glass-to-metal seals serving in the Solar Thermal Power (STP), glass-to-metal vacuum brazed joints were studied. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) analysis were performed to examine the microstructure and element contents of interface seam on the glass-to-metal vacuum brazed joints. Also, the compositional concentration of the interface seam was measured by using energy dispersive spectroscopy (EDS).

Al2O3 and Si3N4 ceramics were joined to titanium alloy (TA6V) and niobium by active brazing. Chemical reactions between the Cu-40Ag-5Ti braze alloy and these materials were examined, and interfacial reaction products were characterized by scanning electron microscopy and electron probe microanalysis. Results indicate the importance of studying the microstructural features of the joints in order to understand better their effect on the mechanical properties of the interface.
