Effect of Long-Term Aging on the Tensile Properties of Nickel-Based Superalloy

Abstract:

The influence of microstructure evolution of a nickel-based superalloy after long-term aging on the tensile properties and deformation behavior was investigated. The results shows that the aging time exhibits an significant effect on the strength of alloy under low strain rate and the elongation decrease with increasing the aging time, but the aging time has no obvious effect on the strength of the alloy and elongation is affected significantly by aging time. During deformation under high strain rate, the dislocation motion is blocked and the dislocation can not release in time, the strengthening phase peak size effect does not appear in the aging time ranging from 0h to 1000h, so the influent of aging time on the strength of the alloy is not obvious. After long-term aging, no precipitation appear in both sides of the grain boundary which leads to the coordination ability of plastic deformation of grain boundaries reducing, so the ductility of the alloy decreases rapidly in a short aging time.
