High Temperature Uniaxial Compression and Stress–Relaxation Behavior of India-Specific RAFM Steel

Strengthening mechanisms of reduced activation ferritic/martensitic steels: A review

“…Obviously, DBTT increases significantly with increasing grain size. Hence, a small grain size (i.e., 10-20 µm) is generally expected for RAFM steels [11][12][13][14][15][16].…”

“…The tensile properties of the material are comparable to those of commercial 9Cr-1MoVNb heat-resistant steels. Since then, many countries have developed different types of RAFM steels, such as the F82H [11] and JLF series steels [12] in Japan, the EUROFER97 steel [13] in Europe, the China low activation martensitic (CLAM) steel [14] in China [12][13], the INRAFM steel in India [15], and the ARAA steel in South Korea [16]. So far, RAFM steels have achieved industrial production.…”

Microstructure and Mechanical Properties Evaluation of Microalloyed Low‐Carbon Reduced Activation Ferritic/Martensitic Steel

“…Reduced activation ferritic/martensitic (RAFM) steel is the primary candidate blanket structure material for fusion reactor because it has low irradiated swelling and excellent physical and mechanical properties, e.g., thermal expansion coefficient and high thermal conductivity. At present, RAFM steel has been widely developed worldwide, e.g., F82H and JLF-1 in Japan, [1,2] Eurofer97 in Europe, [3] CLAM and CLF-1 in China, [4,5] AARA in Korea, [6] INRAFM in India, [7] etc. After tempering, the microstructure of RAFM steel is lath martensitic, M 23 C 6 carbides (M is Cr, W, and Fe), MX carbonitrides (M is V, Ta, Ti, and X is C and N).…”
