alloying additions to increase specific performance factors [13]. Herein, both generations of alloys are grouped together as "ORNL model" alloys unless directly specified.As will be shown later, FeCrAl alloys as a class of materials can demonstrate a wide range of properties depending on their structure, chemistry, and processing. Through combining the databases produced on the GE and ORNL model alloys, as well as other significant commercial and model alloy systems, we have developed the first edition of a comprehensive handbook on FeCrAl alloys for nuclear power applications. This handbook serves to draw from nearly half a century of scientific research but it is known that more studies are forthcoming. As such, the following serves as only the first edition; it is expected that as FeCrAl alloys become a more mature concept, the handbook will be updated and become more substantial.

Blended elemental powders of Fe and C corresponding to the eutectoid composition of Fe–0.8 wt% C are subjected to mechanical alloying in a high‐energy SPEX‐8000 shaker mill. The milled powders and the as‐sintered samples are characterized by X‐ray diffraction, scanning electron microscopy, energy‐dispersive spectroscopy, and transmission electron microscopy methods for their crystal structure and microstructural features. A supersaturated solid solution phase of ferrite with a body‐centered cubic structure and containing 0.53 wt% C has formed after 15 h of milling. This is followed by formation of the cementite (Fe3C) phase with an orthorhombic structure, and its fraction increases with continued milling for 30 h. Spark plasma sintering of the milled nanocrystalline powders leads to the fabrication of dense bulk nanocrystalline steel samples. The microstructure of the as‐sintered sample has a very fine‐grained structure. On annealing at a high temperature of 900 °C, the expected lamellar structure of pearlite is clearly seen on the polished and etched surface. A lenticular structure of martensite has formed in the water‐quenched sample. The hardness of the samples in different heat‐treated conditions is measured and compared with the reference values.
