Nanostructured ferritic alloys are dispersion strengthened and imbued with remarkable neutron irradiation damage tolerance by an ultrahigh density of nano-oxide precipitates that must remain stable under prolonged high-temperature service. Here, prev

A novel method of measuring vaporized chromium species from metallics specimens, in real time, was developed to enable more rapid alloy and coating screening for use as solid oxide fuel cell (SOFC) interconnects. This method, the Ionic Conductivity M

Planar solid oxide fuel cells with yttria-stabilized zirconia electrolytes typically operate at temperatures in the range of 700–850 °C. The maximum temperature is limited by the use of ferritic stainless steel interconnects which offer significan

Nanostructured ferritic alloys (NFAs) were produced by mechanically alloying Fe–14Cr–3W–0.4Ti and 0.25Y 2 O 3 (wt%) powders followed by hot isostatic pressing consolidation at 850, 1000 and 1150 °C. Positron annihilation lifetime and orbital m

An extensive experimental study characterizing the sequence of events that lead to the formation of a very high density of Y–Ti–O solute nanoclusters (NC) in mechanically alloyed, hot isostatically pressed ferritic stainless steels is reported. Y

We model the temperature (T) dependent fracture toughness K jc (T) of MA957 based on a statistically modified critical stress-critical stressed area (σ*-A*) local fracture criteria. The K jc (T) of MA957 is strongly dependent on the specimen orienta

Fully consolidated nanostructured ferritic alloys (NFAs) were prepared by attritor milling pre-alloyed Fe–14Cr–3W–0.4Ti and 0.3 wt% Y 2 O 3 powders, followed by hot isostatic pressing (HIPing) at 1000 °C or 1150 °C at 200 MPa for 4 h. Transmi
