Abstract The influence of C- and B-content on the solidification and high temperature stress rupture behavior of K417G nickel-based superalloy have been investigated by means of DTA analysis, optical microscope, scanning electron microscope, isothermal quenching and stress rupture tests at 950℃/235 MPa. Results show that the precipitation temperature and the amounts of the primary carbide are mainly affected by the C-content, which are both increased with the rise of C-content in the alloy. During stress rupture deformation at 950℃/235 MPa, the fracture mechanism of the alloy can be described as that cracks initiate on and then propagate along grain boundaries. Wherein, the MC-type carbides on the grain boundary could decompose into M23C6-type carbide enriched in Cr, which will reduce the stability of the boundary. Within the composition range of the tested alloys, raising the B-content could increase the grain boundary strength of the alloy during deformation at high temperature. As a result, the proper decrease C-content, while increase B-content can improve the high temperature stress rupture property of the alloy.
