Thermal creep behaviour of the EUROFER 97 RAFM steel and two European ODS EUROFER 97 steels

An Investigation of the Stability of Y2O3and Sintering Behavior of Fe-Based ODS Particles Prepared by High Energy Ball Milling

“…In the preliminary results using our high energy ball mill machine [11], Febased powders were fully homogenized and the value of the lattice parameter of Fe was saturated after milling for 40 min. Eventually, compared to previous experiments [12][13][14], the high energy ball milling method was able to significantly reduce the MA times.…”

9-12Cr Heat-Resistant Steels

“…Thus, oxide dispersion strengthened (ODS) steels such as Eurofer97-ODS and CLAM-ODS steels have been developed (de Castro et al 2007;). However, the microstructures of ODS steels are usually anisotropic due to the manufacture process and their ductile-brittle transition temperatures (DBTT) are very high (Lindau et al 2005;Kurtz et al 2009), though the steels showed better thermal stability Yu et al 2005). Meanwhile, the fabrication involves complicated and expensive process of powder alloying.…”

“…However, ODS steels have several disadvantages: (i) its manufacturing involves complicated mechanical alloying, and (ii) its impact toughness is poor. Especially, their ductile-brittle transition temperature (DBTT) is too high Yu et al 2005). Therefore, ODS steels are still under development.…”

Introduction to Heat-Resistant Steels

“…Thus, oxide dispersion strengthened (ODS) steels such as Eurofer97-ODS and CLAM-ODS steels have been developed (de Castro et al 2007;Olier et al 2009;Klimenkov et al 2009). However, the microstructures of ODS steels are usually anisotropic due to the manufacture process and their ductile-brittle transition temperatures (DBTT) are very high (Lindau et al 2005;Kurtz et al 2009), though the steels showed better thermal stability (Schaeublin et al 2002;Yu et al 2005). Meanwhile, the fabrication involves complicated and expensive process of powder alloying.…”
