DOI: 10.1016/j.jallcom.2017.03.358
Abstract: Abstract The intergranular fracture of materials is sensitive to the grain-boundary segregation of solutes, which is not yet clear for niobium alloys, a vital promising high-temperature material in the aerospace industry. In this study, first-principles… read more here.
