Abstract :
Summary form only given. Recent results have shown that segregation of an atom can change the surface energy and govern mechanical and magnetic properties of materials. In this study, effects of flow rate of hydrogen on the segregation kinetics and magnetic induction were investigated in 30%Si-Fe strips containing 90 ppm sulfur. 100 /spl mu/m thick strips were prepared with methods in a previous research (Heo et al. Acta. Mater., vol.48, p.2901, (2000)). Accumulative final annealing was carried out at 1200/spl deg/C under a pure flowing hydrogen atmosphere of 3 or 10 l H/sub 2//min.
