Both dull and free sides of the as-received ribbons were covered with an iron oxide layer. While a pronounced surface segregation and oxidation of B were observed on both sides of activated ribbons, the fine microcrystalline α-Fe was precipitated as well as B and Zr were oxidized selectively in subsurface layer. On both sides of ribbons, a porous surface structure was formed. The BET surface area was measured to be increasing from 0.11 to 2.68 m~2/g. The principal mechanism of in situ activation has been discussed.
