Abstract: Strain-induced gradient nanostructure formation is an effective method for improving the strength of Mg-Li alloys. However, the microstructural and resulting mechanical stability of gradient-nanostructured Mg-Li alloys during thermal exposure have never been studied, thereby limiting… read more here.

DOI: 10.1007/s40195-020-01046-8
Abstract: Welded joints are usually characterized by microstructural and compositional inhomogeneities, which may significantly degrade their fatigue properties and result in unpredictable failures. The present work demonstrates a novel and simple method to effectively optimize the… read more here.

DOI: 10.1126/sciadv.add9780
Abstract: Nanostructured metallic materials with abundant high-angle grain boundaries exhibit high strength and good radiation resistance. While the nanoscale grains induce high strength, they also degrade tensile ductility. We show that a gradient nanostructured ferritic steel… read more here.
