“…The titanium enriched precipitates and titanium oxide precipitates are usually seen in matrix and on the grain boundary in V-4Cr-4Ti alloys such as VM9401 alloys 13) and #832665 US-heat alloys. 14) But no such precipitation was observed in NIFSHeat1 alloys with the Zr-treated method. Hence, it is emphasized that the Zr-treated method has a strong effect for scavenging the interstitial impurity in vanadium alloys.…”

Microstructural examination and microhardness test were carried out for unalloyed vanadium, V-5Ti, V-4Cr-4Ti alloys irradiated with 4 MeV Cu ions at temperatures from 200 to 600 C. In order to investigate the impurity effect, high purification technique was used. Impurity effects can be seen in the nucleation and growth processes of voids in unalloyed vanadium and those of Ti(OCN) precipitates in V-5Ti. The changes in microstructure due to interstitial impurity could not be seen in V-4Cr-4Ti after the irrodiations below 300 C. The effect of impurity for irradiation hardening in ion-irradiated V-4Cr-4Ti alloys could be seen at 400 C, but it could not be seen at 200 and 300 C. On the other hand, dislocation channels were observed at 200 and 300 C, and the total length of dislocation channels became larger as the impurity level increased. It can be considered that there was practically no correlation between irradiation hardening and total length of dislocation channels due to impurity effects.

“…This strategy is consistent with a minimum-cost approach to technology development. As an example, the two principal choices for structural material are ferritic steels [15] and vanadium alloys [16]. Some fusion-specific work continues on SiC/SiC composites [17], but their development is far less advanced within the world's various fusion programs.…”
