“…The main purpose of Re addition to Mo is to control the recrystallization embrittlement and to improve the ductility in the unirradiated conditions. In previous works, recrystallization temperature and ductility increased with increasing Re content, however, the increase rate was significant at and below 5 wt% Re addition [7,9]. Hence, we can say that 2-5 wt% Re addition would be the best content to suppress both of the recrystallization embrittlement and the radiation embrittlement.…”

“…And it was shown that the Re addition increases the recrystallization temperature of these materials [7] and controls recrystallization embrittlement. Moreover, the Re addition improve the ductility [7,9] and decreases the ductilebrittle transition temperature (DBTT) [8,10].…”

“…This phenomenon may be impeded by rhenium addition. This refractory element also increases strength (Ref 17), ductility (Ref 17,18) and may lower the temperature of ductile-to-brittle transition in molybdenum alloys . Moreover, rhenium increases the recrystallization temperature of Mo alloys (Ref 18) and controls the recrystallization embrittlement.…”

Novel siliconized Mo-Re coatings dedicated to applications in the glass industry are shown in this paper. The study aims at the characterization of morphology, phase composition, and oxidation behavior of siliconized Mo-based coatings deposited on a ceramic-metal substrate. Two coatings with different contents of rhenium were prepared using a hybrid process that includes atmospheric plasma spraying and pack siliconizing. The microstructure, chemical, and phase composition of the obtained coatings were characterized and compared to Mo coating. Moreover, a characterization of starting powders was performed. After the description of the coatings' microstructure, oxidation tests were carried out at 1000, 1100, and 1200°C. The surface condition of oxidized coatings was investigated. The structure of Re-containing coatings after the siliconizing process was comparable. Both were composed of Mo and (Mo,Re)Si 2 -ReSi 1.75 layers. However, in the case of Mo-44Re (wt.%) coating, a higher concentration of rhenium silicide was observed compared to that of coating containing 15% Re. The Re-containing silicide layers were characterized by a presence of lower content of hexagonal MoSi 2 compared to that of non-alloyed MoSi 2 . The oxidation resistance of both coatings containing rhenium was comparable; however, the one with a higher amount of Re exhibited slightly higher durability in high-temperature oxidation.
