Abstract: [eng] [cze]
Ion beam sputtering by Ar+ ions was used to investigate 99Mo tracer diffusion in Fe76Mo8Cu1B15 alloy in the temperature range 548 – 648 K. The experimental samples were prepared from ribbons of Fe76Mo8Cu1B15 alloy in as quenched state q, and after pre-annealing at 683 K for 1 h (state a1) and at 743 K for 1 h (state a2). The penetration profiles were obtained using serial sectioning method and consist of two parts suggesting that two different diffusion paths are operating. The Mo short-circuit diffusivity P was evaluated using both LeClaire’s analysis and Divinski’s theory derived for transition type-A/B regime in coarse-grained materials. Odprašování iontovým svazek ionty Ar+ bylo použito ke studiu difúze 99Mo ve slitině Fe76Mo8Cu1B15 v teplotním rozsahu 547 - 648 K. Experimentální vzorky bylůy připraveny z pásků slitiny Fe76Mo8Cu1B15 ve třech různýc stavech. Penetrační profily se ssetávají ze dvou částí odpovídající dvěam různým difpzním cestám. Byla vypočtena difuzivita P jak z LeClairovy analýzy tak z Divinského teorie pro přechodový režim A/B.
