| Abstract | Boron segregation and boride formation at grain boundaries are generally accepted in Ni-based superalloys. However, the addition of boron was found to result in the formation of a high density of nanosized M5B3 (where M is a mixture of Cr, Mo) particles in gamma/gamma ' eutectics of a Ni-based superalloy during high-temperature creep in this work. M5B3 phase precipitated at gamma/gamma ' eutectics keeps a well-defined orientation relationship with the eutectics, which is [001](gamma/gamma ')//[001](M5B3), (020)(gamma/gamma ')//(130)(M5B3). And these nanosized borides could block dislocation slip, result in stress concentration surrounding gamma/gamma ' eutectics and facilitate crack initiation at gamma/gamma ' eutectic/matrix interface during the creep at high temperatures. |
