New Nuclear Materials Data Have Been Reported by Researchers at Los Alamos National Laboratory (Fracture behavior of 9Cr nanostructured ferritic alloy with improved fracture toughness)
By a News Reporter-Staff News Editor at Science Letter -- Research findings on Nuclear Materials are discussed in a new report. According to news reporting out of Los Alamos, New Mexico, by NewsRx editors, research stated, "Nanostructured ferritic alloys (NFAs) have been considered as primary candidate materials for both fission and fusion reactors because of their excellent creep and irradiation resistances. It has been shown that high temperature fracture toughness could be significantly improved by appropriate thermomechanical treatments (TMTs)."
Our news journalists obtained a quote from the research from Los Alamos National Laboratory, "This article focuses on the static fracture behaviors of newly developed 9Cr NFAs with improved toughness. Optimal TMTs resulted in high fracture toughness at room temperature (>250 MPa Vm) and in retaining higher than 100 MPa Vm over a wide temperature range of 22-700 degrees C. Significant differences were found in fracture surfaces and fracture resistance (J-R) curves after different TMTs."
According to the news editors, the research concluded: "Unique fracture surface features such as shallow nanoscale facets decorated with shear lips and flake-like grains were observed in high toughness specimens. ."
