dcterms:description
Diffusion phenomena in multi-component metallic systems have been studied at diffusion joints Ni/Ni3Al-Fe and Ni/Ni3Al-Ti. Chemical composition of the found intermetallic compound corresponded to the phase gama´ of the ternary system Ni-Al-Me. At first, specimens in the form of cylinders (diameter 10 mm) were joined by two technologies: electron beam welding and resistance butt welding. The specimens were placed in evacuated quartz ampoules and annealed at the temperature 1050 °C for the time 100 hours and then quenched into water. They were examined metallographically in the states before and after the annealing, their micro-hardness in the diffusion joint area was measured and the global (ICP-AES, SPECTRO MAX) chemical analysis was carried out and concentration profiles of individual components were explored by the X-ray (WDX, EDX) micro-analysis. The obtained concentration profiles were evaluated applying the modified Matano-Boltzmann method utilizing the concentration curves for which optimum type Diffusion phenomena in multi-component metallic systems have been studied at diffusion joints Ni/Ni3Al-Fe and Ni/Ni3Al-Ti.
