using Ion Beam Sputter Deposition (IBSD) method, sputter etching (SE) followed by thermal annealing is effective substrate treatment to obtain highly (100) oriented
-FeSi
on Si (100). However the best condition of these treatments are not yet known. In this work, the effect of sputter etching (SE) together with annealing process on the orientation of the film is investigated. In prior to the deposition of Fe, the substrate is irradiated by Ne
ion with various energy and fluence followed by thermal annealing at 1027 K for 60 minuets. The overall results show the most suitable SE condition using Ne
ion on IBSD method is the energy of 1keV with the fluence of 30

ions/m

JAERI and JNC have begun the cooperative research of evaluation techniques of structural material degradation in FBR and LWR, which based on magnetic and corrosion properties along grain boundaries. Magnetic method has been proposed as the one of the non-destructive detection techniques on the early stage of creep-damage before crack initiation for aged structural materials of FBRs. The effects of applied stress on natural magnetization were investigated on paramagnetic stainless steels having creep-damages. On the other hand, corrosion properties and magneto-optical characteristics of ion-irradiated stainless steels in the vicinity of grain boundaries were estimated by AFM and Kerr effect microscope, respectively. These degradations were induced by changes in characteristics in the vicinity of grain boundaries. It is found that the initial level of progressing process of damage can detect changes in magnetic and corrosion properties along grain boundaries of aged and degraded nuclear plants structural materials.
